Marshall Brokenbreaker

The owner called this amp the "Brokenbreaker" because it breaks down all the time.  It's a 1970's JMP50 50W Tremolo Lead 1987T circuit that appears to have been through a lot in its lifetime.

This time, one of the EL34s had shorted.  This circuit is very hard on new production EL34s so I installed some extra protection features and lowered the grid leak resistors to keep the tubes happy.

This was my first attempt at fixing the "Brokenbreaker" - hopefully it's my last and the owner can start calling it a JMP50!
