The black wire at 10-o-clock (back side of the ouput resistance Ohms selector - middle circular array at the top) has come away from the solder joint (hard to see) - but seems the only obvious...

I'm not sure ... could this be Jim Marshalls signature on the test slip? I thought he wasnt involved in this side of things. Would be nice to know who it was though. Shame the rest of the label...

Also looks like 3 more diodes in the Lead Channel section besides the LED. I just dont see how that switch by the pill pot can get signal to the lead channel.

That’s looks as good as the top on my 60th anni R0. Sweet!

Excellent work William !!!!
