Did you ever find one? I have this amp but not the power supply. Looking for any information on what voltage the external transformer outputs and the wiring colours.
Thanks mate! I missed this reply but managed to work out from other circuit indicators that it was between 35 and 40 VAC centre tapped. Went with 35 and took a chance. Has been providing sweet tunes for a year and a half.
Really appreciate you taking the time to reply and sorry I took so long to thank you.
