I saw this Gray Bench teardown video the other night, and the values looked a little different to what I’d seen on other Sun Face schematics, so here it is.
If you don’t feel like watching the video, the key difference: 51k resistor on the collector of Q1. The rest is all pretty standard for a Sun Face, although it does mention biasing the collector of Q2 to 5v, which is a little hotter than the usual 4.5v that is often referred to for fuzz faces.

And if you think this is a lot of vero for not many parts, you are correct. It’s still kind of small, and will easily fit in a 150b enclosure, so why bother making things hard for yourself by crowding a board? Besides, you’ll need some room to lay the germanium transistors flat.
