I love the clear Plexiglass mounting plate above the caps. Also the solid copper bars that the Mosfets are mounted onto.
Finished my F6. Still some tidying to be done.
Many thanks to Nelson Pass and 6L6 and all the other forum members posting here.
PSU is:
Sounds very good without any hum.
Not sure whether it is better than the F5 (v3) I have built before in the same case.

@Jacruzer787 Thank you! I had no success using a transformer-based/ linear PSU. I always had a little bit of hum coming not from the speakers..
And probably less weight as well. I know some people had made some covers for the autoformer, cant remember where. I also don’t know if they fix hum issues. In any case, no need to fix was is not broken!
I don't think I've posted this here yet: I cleaned up the DC wiring a bit on my Zenductor 2 (Burning Amp 2024) in a Modushop Galaxy 2U chassis. I divided up the auxiliary loads: the bias DVMs are now properly powered from their respective amplifier DC supply, and the preamp and the push-button LED (few 10 mA each) are now also split up. All hooked up via an original Lüsterklemme from the old country (or maybe IKEA also uses them here?).
