I just bought a 220v Roland Jazz Chorus 55 that was adapted for Canadian use with a voltage up-converter. It looks like the power transformer is dead. Pilot light does not come on and the secondary coil reads zero volts. Primary coil reads 235v. Fuses and switch are ok. (I wonder whether the 15 volts over-voltage on the primary blew out the secondary?)

Can I put in a new tranny that will convert the amp to 120v/60hz? The current 220v transformer seems to output 24v/1.5A at two points. As far as I can tell, those two 24v leads power the entire amp. Can I just get a 120v transformer with two 24v/1.5A outputs and plunk it in? The service manual says that 220 and 120 PC boards are the same. It *seems* like they both run on 24v.

I've built three tube amps, so I'm not a complete noob, but this is my first SS amp and my first Roland, and I've never worked with Euro voltages. I'm good at following directions, though.

Thanks!
