x0xb0x Etudes - pt 4

Envelope + VCA done.

Desoldering sucks.

First that damn wrong transistor, then the wrong pot. Got to watch those differences between D and B pots! I do have a solder sucker now so it's helping some.

The only other issue, after the envelope / gate section my tests weren't passing. It was either reversed or loose transistors around Q36 - I'm socketing all the 733 transistors so I can swap them out for higher beta ones if I ever feel like it. Anyway, they were loose, but once I touched up a couple solder points and stuck them in more firmly, the gate tests passed just fine.

On to the headphone and mixer/amp section.
