Rick Erickson	Re: Converting UK Power Marshalls to US ? I don't recall seeing many, if any 50 or 100W heads from the 60's & 70's (in the USA) that didn't have multi-tap PT's. You will need to open it and see if there's a bunch of un-terminated colored wires coming from the PT primary and chose the tap that gives you the closest to 6.3V on the heater supply. you can probably consult the Marshall schematic archives on the internet to get the color codes for the various taps.
