And it was designed for 110 volts

Paul that is exactly what I told him over on DIY audio.Usually the one's bought on Ebay were halved from the 220vac that China uses and what I ended up doing was series connecting 450v electrolytics as they were swelled and then I changed the supply resistor to a higher value feeding the driver and preamp tubes as the B+ was 34v high..The outputs were higher as well but I didn't worry about it as much especially since the 845s could handle much more than the 720v the Music Angel was feeding them.
They should have designed a power transformer that was for the US and Canadian markets.
