Title: Mike Matthews Freedom Amp repair help
Post by: jolyamp on December 30, 2015, 10:23:21 AM
I am trying to help a friend with his Mike Matthews Freedom Amp from the 1970's.  The large capacitor came loose and tore most of the wires off.  It also damaged the bridge rectifier mounted to the capacitor.  I am looking for a schematic or connection diagram for the capacitor assembly and where the wires mount to the circuit board.  Any recommendations would be appreciated.
Thank you

In case you didn't solve it yet:
The Freedom Amp was originally powered by 40 D sized 1.5V batteries  :loco , a truly revolutionary concept, for a 60V DC sungle supply.

That huge battery supply had 2 terminals: negative went to amp ground and positive to a power switch.

Although the idea was cool and you could *really*  play your guitar LOUD while skydiving  :duh , on top of the Everest or in the middle of the jungle,
