My ms-300 B was certainly not designed for servicing..
Along the very back there are 12 wires (In between the 50w cathode resistors) that need to be soldered to standoffs and they are within 10mm (or so) of each other.
This is always an exercise not unlike the game operation, and instead of the buzzer, you get a puff of smoke!
None of the other connections offer too much trouble, but I literally hate working on this amp because of those 12..
I was thinking another daughter board across the back that's much wider giving better access and raising the connection points to gain better access...
or may be as silly as it sounds, 2 6 pin connectors (1 for low voltage and one for high voltage) ??
Does anyone have any tricks or methods that can eliminate the problem all together (Besides the obvious!) ?

Not sure from the photo where this is, but is there room to somehow install (glue?) pieces of Spauldite or similar phenolic industrial electrical power isolation barrier material? You can hold soldering irons against it and it just discolors and now that I think about it don't recall it even stinking, at least enough to dominate the stench of mass quantities of silver soldering.
