NEW ELTIM products
20 June 2018
More than once we were asked if we could build amplifier modules in "ELTIM style" with the very well klown and behaving LM3886 amplifier IC of Texas Instruments. After some investigation we found out that there are a lot of those, all very cheap, small and using cheap components. If we wanted to do it as requested, we needed to use way better parts and PCB's. This results in higher costs..... After some thinking we decided to go for it and designed several modules with this LM3886, as with our other Amplifier modules available with different power supply capacitors:
While concentrating on that, we also found it's brother, the LM 4766, beiing a stereo version (8ohms only!) and made similar ones with those as well. You even can combine all modules from both ranges in a compact pack and even add a "booster" pack containing a group of extra power supply capacitors. Both versions are available for connecting to a power supply, but there are also versions with on-board power supply where you just have to connect a transformer. Now we hope you will follow as well and buy these nice sounding amps. Price is higher than on Alibaba/Ebay, but the sound is way better and they last forever. ELTIM style, as requested -)

We finished developing a wide range of switching DC/DC voltage converter/regulator modules. With these modules you can extract energy from about any supply source (even boat/car battery) and convert/regulate it into the known low voltage supplies 3,3V; 5V; 12V or 15V or symmetrical and even mixes of them in an energy efficient way. Suppose you have 60V already available for your class-D power amplifier. Hook up one of our switching modules and you also have f.e. ±15V for a preamplifier/DSP AND 5V for digital circuits available. We have all versions with a screw terminal and with headers, fitting most of our Power Supply modules directly.
Here our first built model: 9-36Vdc in, ±15Vdc (0,33A) AND 5V (4A) out.

We now modified our PS-UNxx universal Power Supply modules for high power purposes and all have a square shape now. They all can be mounted over a corresponding type of transformer. Due to the extra PCB space we were able to mount more, and more types of capacitors than before. We also modified them in a way that besides our linear functioning Voltage Regulator modules, also our brand new switching DC/DC converter/regulator modules will fit. WIth these, you can extract low voltage Supply voltage(s) from a high voltage system without significant energy losses. Also, the output(s) are regulated.

By several DIY'ers we were asked to construct a serious DIY amplifier kit based on the LM3886 from Texas Instruments. With this IC one can make around 40Wrms into 8 ohms. We KNOW that you can buy modules like these all over the internet for a few dollars! Before we started this project we studied them and found out that these are just hobby projects where all the PCB and parts rules are ignored and by far do NOT meet the LM3886 specifications. So, you get a module with all kinds of "handicaps".
As a serious company we cannot afford to do something like that, so for those who want a serious module, capable of delivering what the IC itself can, we are developing two kits/modules. One has to be connected to a Power Supply, the other one has it on board already and there you just have to hook-up a transformer.
Since we buy all our parts over excisting distributors with according prices, ours will not be only a few dollars, simply because the IC as well as the PCB each cost more already.

We are working on a wide range of switched mode Power Supply modules. Other ones? YES, but these are suitable for high qualilty audio stuff and other professional gear. We cancelled out the RF-residual ripple (caused by the SMPS module) on the voltage rails by adding LC-networks and some other components.
They will be available soon with single and symmetrical outputs, symmetrical versions with extra +5V and versions with 5V and 12V.
Read here the PRELIMINARY datasheet.
13 september 2016:
We developed a range of volume control/buffer modules, forming the heart of f.e. our own preamplifiers.
Attenuation/gain can be set by a 0-4,8Vdc signal and/or by SPI serial data.
- VCA-2181x, three models in reference quality, using the higest quality parts and fully seperated channels.
- VCA-2180x, three models in High-End quality, using very good quality parts. Seperated VCA's.
- VCA-2162, a more cost effective version with dual channel VCA and buffer IC's.
All connections of all modules are the same, so they can be exchanged. You can even use the same software.

Our prototype monoblocks based on CS-40ps RQMB modules are running a few months now in a normal living room environment, just as you probably would use it. From the start they are running perfect and last week we finished them with the mounting of our Bin/Lout-1200 balanced input circuits.
Both models are also available in ready built monoblock amplifiers. We decided to release the CS-40ps RQMB and HRQ versions today, on Louis' birthday 13/8 -).
At first we believed power would be limited because of the quite small cooling surface of the cabinet, yet even while running the small RQ version at around 200W@4ohms they only get hand warm, even with a way higher idle current as we recommend in our documents.
8 August 2017:
Our ELTIM amplifier module CS-40ps HRQ is reviewed against HYPEX NCore by Uniqueradio.nl (in Dutch):
Some will be surprised about the outcome -) LT
14 october 2015:
We found out that there is a lack in availability of (quality) symmetrical Power Supply modules.
Find them now with integrated Talema 700000 series potted toroidal PCB transformers in a range of 5-25VA under ELTIM Ampifier modules/Power supply modules/PS7xx ! Very low magnetic field, hum and noise rates due to fully equipped PCB's.
We only use high grade components like PANASONIC FR (10.000 hours @ 105ºC) capacitors, small caps over the rectifier diodes, etc.
If a regulated symmetrical voltage is required, you could add on of our VR-modules (as in the picture blow) to it. VR3 and VR-4 are adjustable. So, with these you even could make a small (±1,5A max) , symmetrical laboratory Power Supply !
In similar way, we also made more regular single voltage variants. With these you can add a 317 (TO220) Voltage regulator, incl. heatsink and extra parts. In that case there is an adjustable voltage available as well.
Due to the low profile toroidal trafo's, height is only 23-28mm, so you can even use them in 40mm casings.

In the little time we have in these busy days, we finally managed to built our DEMO amplifier, a A2300 HRW model with 16A EXICON Mosfets. Every time again it is nice to watch and hear a product from your ow hands coming alive and rewards you with a fantastic sound. But then again, who am I ??
Next week Bert Oling of oldest dutch magazine HVT will review it. Other reviewers are most welcome. Soon it's your turn, but you have to line up by now...... € 500,- downpayment required.
A2300 HRQ with 2x CS-40ps HRQ, 2x VS-20 (and MCap250-2,2), 2x VR-3/30, 2x 160VA/ 2x 30V trafo's and Kacsa connectors.
Last week mr. Bus built this also in one weekend after buying built and tested modules.

It appeats that some of you dislike the Mundorf Mcap250 we use as input capacitor on the VS-20 modules. Although we mention it in the corresponding document you can use the DC-input of any VS-module and connect ANY quality capacitor you like, hardwirded to the RCA input and DC-in connection of any VS-module. In that case, the already on board capacitor is NOT used and so NOT in the signal path! We used this cap in order to allow people to buy an affordable VS-module and at the same time, allow people who want to spend more money and/or prefer an other input capacitor to do so. Since we have to take in mind that the VS-20 can be mounted in all cases, we can't mount a bigger one either. Perhaps later, a VS-30 module? Similar to VS-20, but 50mm instead of 35mm high probably. Let us know BUT, the comments you can read so far, are with Mcap250........ So what more is there to dig out from the bottom of your music data????
Please take in mind that you CAN mount any high quality capacitor this way on our IO-modules, like in the picture below where a Mundorf EVO MESGO-2,2uF is mounted.
If you are using a balanced IO-module there isn't any capacitor in the audio line, from input to speaker output!
28 july 2015:
Despite the fact that the datsheets list april 2013, just last week of july 2015 OnSemi announced that the quite new STK modules program completely will be discontinued in short notice. We wanted to use these in the recently announced ELTIM HYBRID modules.....
So, despite all the time we spent in developing, we will not produce these nice modules. Info bulletin

This week our prototype amplifier was collected by some audiophile guys, now using Accuphase class A, Jef Rowland, Quad, etc.
We got a first message from them after one evening of listening already:
We are crushed by the musicality. B even became emotional.
Super, what an amazing amplifier.
So far, "B" could only become enthousiastic like this while using expensive Class A amplifiers.
1 july 2014
Our own and first amplifier modules are ready for sale now. Dealers and OEM are most welcome as well
We finished our Elite 621 mkIV DIY speaker system.
Read the test in Klang & Ton of coming December issue !

We developed our own PCB for assembling high-end crossover components. It became very versatile, since you can use ALL Mundorf (and probably other brand) capacitors, Air and Foil coils (Air, Aronit and I-Cores)
and Mundorf MR5/MR10 resistors. Beside that you can use multiple capacitors (f.e. two Supremes antiparallel) in the crossover function and we even provided space for the new Mundorf impulscapacitor MCAP 1000 or RIFA radials if you like them more. You can connect them with 6,3mm Faston blades or a 6 pole screw terminal. Last but not least you can use this single board for SIX different types of crossover by assembling them in a different way as 12dB HP, 6/6dB BP, 12dB LP (also for low frequencies) and 6/6dB Serial (also for low frequencies) crossover. The size of this PCB is still only 100x160mm Euro format.
We plan to design a similar PCB in size 120x200mm to fit even larger/more components.

We will be present at Dutch VAD show in Veldhoven, near the Belgian border ay 17-18 october. We will have a small booth in the Brabantzaal, presenting the new Morel drive units and a selection of the rest of our program like cabinets, Mundorf components, connectors, cable, DIY speaker designs, etc.
July 27, 2009
After waiting for over half a year the fabulous subwoofer UW 958 with 130mm hexatech extermal voicecoil and handcoated paper cone has finally arrived.
July 22nd 2009
After introducing MUNDORF crossover components in the Netherlands already in the begin of the '90s, our founder had to rest his audio plans in 1998 due to very dense activities in the telecom scene.
Like seven years ago with MOREL, we are extremely happy that Mundorf gave us the opportunity again to restart sales of their fantastic crossover components and other fine stuff like silver/gold speaker cables, etc.
As you are used to by now, we will give more and more information in a readable way, for everybody who want to know more about the MUNDORF program.
With this new program we believe we are quite complete as a "on stop shopping" webshop for the ardent audiophile technicians.
July 1st 2009
We uploaded a higher grade version of our webshop software. Now you can login after entering your data once and use this all the time without reentering it while ordering. This is not particulary neccessary though. In the ordering process you still can decide to enter these data and use it later again.
With this new version another feature became alive: you can make a "wishlist" meaning that you can add the products of your interest in this list, without the need of trying to find them again. You can order from this wishlist items too. This is especially a help if you are ordering the same products more then once. You can even send one or more items by email to a friend, collegue, etc.
June 26 2009
We supply HYPEX amplifiers for half a year now to the industry market. We just got permission to put them in our webshop too, so we did at once.. Check out these very well performing Digital amplifiers.
We use the UcD400 in our PA-DIY design PA-82. The prototypes are used by a friend and they and the audience are amazed about the quality of this system.
After pressure of entering all these new products (even more to come.....) we will design some of our cabinets in a way that you just need to assemle your fantastic amplifier.
June 15 2009
We made arrangement with a European manufacturer of the most fantastic DIY cabinets we have ever seen. Check out our Electronics Cabinets parts for details. Instead of listing all possible cabinets as an Article, we decided (thinking as wanting one ourselves) to enter the most basic model as product. Then you can select all the options (wiht increase of price) available, ending in a total price.
This company also supplies the 10mm brushed aluminium frontpanels you were looking for, and even produce a T-amp based casing. We will also release some models where HYPEX amps will fit.
June 12th 2009
We made agreements with one of the largest European manufacturer of cables, connectors, etc. With their program our product postfolio increased dramatically. SInce we all are hobbyists too we tried and believe we sorted all products the way you want them to see, f.e. if I want a RCA connector to be mounted on a 6mm cable, I want to find it in a group Connectors>RCA>6mm. So we did.... This results in more groups with less products to sort from.
May 18, 2009
We finished the raw version of a very nice looking and sounding compact speaker system based on our exclusive Intergra 6 hifi coaxial drive unit.
This slightly tilted triangle shaped speaker wil fill and fit any smaller and regular living room. The final one will be slightly larger. Soon more at our Design pages.
April 23, 2009
We surprise everybody with a special coaxial drive unit model, called INTEGRA 6 hifi.
This 16cm unit uses a sanded paper cone, 54mm Hexatech voicecoil and is powered by a Hybrid magnet system. It is using the same Uniflow basket as the CAW 638, EW 638, etc. Parameters are set for use in small sealed as well as in vented cabinets. The tweeter in the acoustic centre of the woofer is a handcoated silk dome with a 28mm copper voicecoil. The midrange voicecoil is protected for FOD (Foreign Object Damage) material, so you can damp the box with any material without risking damaging the coil with it. Both units have seperated binding posts, so you can cross it the way you prefer. It can be used as a seperate unit as well as a very well performing mid/high unit in a multiway system. It is even in stock........
April 15nd 2009
We also finalised our CA 621 DIY project based on CAW 638 and CAT 308. A 6/6dB serial crossover is used again for correct phase response..
April 2nd 2009
We finalised our Elite 620 DIY project based on EW 638 and ET 338-104. A 6/6dB serial crossover is difficult to tune indeed if you cross on the edge of the tweeter range.......
March 24th 2009
Finally it is available: the most impressive 9" subwoofer called UW 958. Driven by a huge 130mm Hexatech External Voice Coil with a load capacity of 500Wrms, it
will bring you the lowest, yet fast bass response you can imagine......
March 20th 2009
We just finished our new stand/bookshelf speaker called CA 620. It is based on CAW 638 and CAT 298, beeing the most cost effective 6" Morel based system.
February 15th 2009
Our first model from the Elite range, called Elite 621 is ready now. With the ECW 638 woofer and ET 338-104 tweeter absolute quality sound is guaranteed.
We finished our first model using the new drive unit program. This floorstanding CA 625 is equipped with CAW 638 and CAT 308.
