Hi Peterphuket,
Thanks for your valued views on my build.
After the numerous delays, my final beast will remain as it is.
Transparent labels? Maybe something to think of in the near future.
Listening pleasure has been is still is great, with many jealous neighbours!

Kay, please see post 613

@Kay, I agree with you, it is a fabulous pre-amp and everytime I thinking can I build a better one? Until now the answer is negative.

Friendly regards

Yes, I have the German issue of this article handy, and there are still two complete Q-Watt kits in my shelves, waiting to become assembled.

Best regards!

I think I've been saying this yet: I've bought some rather cheap 24 V 5 A SMPS that I'll open and modify (remove the internal link from PE to the negative terminal, tweak for 27 V output voltage) and build a series connection of four of them per channel to get 54 Vdc.

Best regards!

Default Elektor Q-Watt & Preamplifier 2012

Preamplifier 2012 (1) - introduction and line-in/tone/volume board (110650) - Elektor LABS

A few more wiring connections left on my Elektor Preamp, but that's another forum thread (there are a few).
