In Reply to: Allen 60 watt amps..I Mcshaned the first one to compare. posted by MIchael Samra on August 13, 2006 at 20:32:36:

I had managed to find a schematic for an allen 6550 amp on line but it was somewhat different than my amps..The one on line has a 12ax7 in addition to the 2 6sn7s and the ef86 along with a 10H choke as opposed to the 15H in mine.
THe caps that I thought were doubler caps arent..The transformer says 525v AC RMS and what they did was hook the filter caps in series so they could drop the voltage down for the driver tubes..I see a lot of heat sinked power resistors but being this was enclosed in an organ,I would imagine that prompted a lot of their ideas.
