Are you interested to build this exceptional AMP?
Great idea and initiative Rudi!
Provided the NJL power-transistors will be obtainable, I`m definitely very interested (in about 10 amp boards, depending of the PCB dimensions, maybe even more).

BTW: with "PSU-PCB", do You mean the (regulated) front-end supply?

While the silk screen component designations would be a big step forward the present layout does not have much spare real estate to allow this to happen. In fact the layout is so tight that there is practically no scope for parts substitution whatever.
Something I found using Panasonic 1,000uF capacitors was that there is not enough space to fit the output Zobel parts. Maybe the thru plated holes for the output devices need to be moved a few mm further apart. Either that, or move the Zobel parts along the board towards the main reservoir capacitors to avoid the squeeze between the pairs of 1,000 uF.

thank you for your interest.
I will open a group-buy thread for this AMP very soon.

Best regards - Rudi_Ratlos

Count me in for 8-12 complete boards and matched transistors.

Yours Sincerely

Call me strange BUT if I had a choice in the matter I would
choose black for the pcb colour not red....
