JM, Thanks for finding the main supply on the schematic - I noticed the other supplies but couldn't figure out where the higher voltage supply was located. So where is the center tap located for the transformer? Was I reading the voltage incorectly and should have been measuring from the CT - that would give a reading of around 60VAC.
I guess I'll have to unsolder all these transformer connections and measure each "tap" from the PT to see what's going on?
Do you think this amp is a "boot-strapped" design where you run the low voltage (5V) supply for idle and low power and then bring in the larger supply to drive peak voltage? Class G??
A new transformer is going to coat 200 euro - I assume this amplifier is worth that cost?
