Hi... I have an export Music Man HD150 (150watt) with a blown power transformer. I found someone locally to rewind a new power transformer but we can’t figure out the actual secondary power output values to achieve the required values stated on the schematic http://www.ernieball.com/mmonline/techin fo/old_amps/2475-150_&_2275-150.pdf

The Primary is blown and i can't measure the outputs ...Does anyone here can provide the AC outputs of the secondary ?

Your kind help much appreciated
