Finally!
And, before anything else, thank you to Markyboard and everyone else here in in the groups that helped me figure out things as I went along. This was a big job, no question about it. A lot was changed, and I am sure it’s been improved. I did a burn-in overnight after tuning all 6 voices and still tuning up perfectly. Decided to button her up and put her back in rotation with the other classics…
Final oscillator tuning and calibration:
New Noctua fan:
Voice boards (new sockets installed for all Curtis chips and all ribbon connectors, along with full re-cap and some 4016s replaced):
Close-up of voice cards with new trimmers installed:
2 of the 3 EPROMS for the 2.4 OS that broke. my. bawls. trying to burn until I gave in and got a good burner and eraser:
All buttoned back up:
Quite possibly the best thing any Memorymoog owner could see:
Of course, I still have my doubts because… Memorymoog… but, I’m honestly very pleased with how this all came out, and it really taught me a lot in terms of really reading and understanding the schematics and the different circuits which is kinda late considering I’ve already been in it messing around, but really I feel a lot more confident repairing other big jobs now.
