Why three fqpf8n80c? Shouldn't even one do if proper heat sinked?

Thanks a lot sir.

A very beautiful amplifier. Many congratulations.

That looks very nice indeed. Well done (as always)!

The two 1K gate resistors in place, 240R as source resistors (not 250R – took what I had). No LED and its 175Ks and no A bridge. Is there more to consider. The lower source resistance couldn’t be the problem or…?

Some time ago I did the new KGSShv board with Only IXYS parts. With power on both channels showed -380 V. Same thing both boards. Today I replaced 10n100d with c4686 and then it works. Have anyone built KGSShv new board with all IXYS parts and have it working?

Great, well done. Like your case – is it your own design? could it be bought somewhere?

Beautiful pictures, RiStaR. Congratulations.

Yes, that was wrong part number. I’m sorry - it was late and I mixed up the numbers. I use the insulating washer # 7721-3PPSG and I use a tool to press the washer in place. So far it works without problems for me. I have two working T2 and some other stuff. But I can see the advantages using PEEK screws and it seems that the torque they provide is good enough.

In my opinion nylon shoulder washer (mouser # 534-9902) and stainless screws will do. Cheaper then PEEK and you can apply “correct” torque.

Very nice. Beautiful front and top cover. Like the volume knob.
