Hello.
I have bought this boards supposed to be from true Goldmund amp Telos 600 but I’m pretty sure they are not Goldmund boards because they doesn’t match to telos 600 schematics.
Maybe this is a protect already discussed in this forum. I need the schematics to install the fets and some transistors that are not populated. My big concern is the N jfet that it is not 2N5565 but U402 and I don’t know if this is just something to install it or the input board is designed for U402 Jfet.

Looking very nice .
Can you give me some more info regarding which toroids ( transformers ) used ? And how you have wired everything especially grounding and the feedback wire . And what I want to know , how does it sounds .
I bought the same from Marcel , I know him personal .

I used, for each channel, 1 toroid 800VAC (800V) 230 to 2x42VAC. After rectification I feed the boards with 2x58VDC

GND1+GN2 bridged and straigt to 0V (GND) at psu
GND2 and straigt to 0V (GND) at psu
installing front end board with spacers up the amplifier board will feed GND to front end board, so I only installed the feedback wire from the FE board to AMP board.
Speaker protection feed with 0/12VDC from a different transformer. The right one from the first picture in the upper post.
Case Led feed with a different transformer as well (in the center in the first picture in the upper post).
Sound? well I really think this build worth every euro spent. Fast, dynamic, detailed and very warm and rich sound.
If you need any detailed picture, let me know.
