Hi, since you have this amp, could you please do me a great favor? I bought one KA-1000 also, unfortunately without the power supply.. The device had only 4 burnt transistors, which I already ordered from digikey original sanken, I have already ordered two torroidal transformers 2x45V for the +-62 Volts (primary 230V). And I am a little confused about the third transformer that I want to order, that I want to use for the +73, -75 voltages (yes in the schematic it seems like -75 not -73, at least at my copy), So, if I am right I will need two secondaries, one 54 and one 52 Volts.. In the original power supply one transformer should have this secondary with violet/blue cables - I think this should be the 54V one, and the other transformer, with brown/blue, the 52V one... could you please measure the voltages at the transformers secondary outputs? and also with how many volts at the primary? (I will then calculate how much should the voltage be, with a 220V input, and order that value for 230V). You will help me a lot.
