Success! It plays music. Now I have to put it away safely until I can get one of those "Greedy Boyz" cases for it.
A big thank you to all those who made this possible!

I never doubted the great ZM. Just happy that I was able to complete it without any issues. The markings on some of the three legged creature was very hard for my old eyes to read.
But does it play all music?
start with Hoff and Richard Clayderman
everything after will sound divine

Yes.
For piece of mind you could add the same heatsinks as on Q1/Q2.
But ZM likes them naked

I’m noticing M1 & M2 run rather hot (they do pass the 5 second rule). This is normal I hope?
your call
they're twice colder than TO220 and likes in Japanese preamps, amps and whatever of Yore
smallest TO220 htsnk will ensure better sleep, but not longer ..... longevity

Oooooooooh - Pretty!
Good looking relays there. 😉
Sleep was fine last night…guess we’re good.smallest TO220 htsnk will ensure better sleep…

after looking at your pic again - they will be colder once you have buffer JFets in place
without them, M1 and M2 are sinking full programmed current
6L6,
Can you please indicate the Mfr. Part No. of the 'AC Power Inlet' you used in your build (image below)?
