Goldmund GM27 clone

[m0rten]

Hi
I have just bought a Goldmund GM27 clone working on one channel only.
Does anyone know this specific PCB?
I cannot find any schematics for it, although I have plenty for other variants of this amp.

What I was curious about was the two power input sections at the bottom of the PCB. Why is only one of them connected? Is it just an alternative input?

Thanks for any help!

Thx for schematics! The PCB in your link shows a somewhat different version, with not the same power connections.
Guess I'll have to find out the tedious way! 🙂

Btw, I found this on AliE. Very close to my PCB, with trafo on both power connector.

Hi do you mean that just one channel is working ? how does it sound ? i have listened some video on Youtube and i am amazed by the lack of noise and the snapping sounds I have seen the schematic and wow ... complex it is
