Ok... I disassembled the entire big board. Dismounted both TIP50's from their heat sinks. (The transistors were mounted properly all along, I just disassembled and reassembled in the same order.) Replaced one thermal insulator pad that looked iffy. Reassembled everything including replacing all the hook up wires for the big board.
Just fired it up and everything seems to be working.
Here are the new voltage measurements:
Big Board:
OA= 111.4
OB= 109.0
G= 0
B+= 185.7
I hope this is the end of it. Gonna keep an eye on it for awhile. Can't thank you enough for your patience and understanding--not to mention your great wealth of knowledge. It's a pleasure to be a part of the Bottlehead community.
