Hi.  I have a Mesa Caliber 50 that I need a European replacement power transformer.  Anyone know where to get on?

Hi Sluckey.  My problem is that I can't buy from Mesa directly, I get sent to a company in Finland who again refers me to another company in Norway, and they are not very interested in helping out.  I know MM makes one, but very expensive, 250$ plus shipping.  So I wondered if anyone knew of any replacement PT'S?

It's M-B's riff on a "50 Watt Fender". Will take the PT from a 2*6L6GC Silicon rectifier Fender. Need 50VAC tap. Do not need 5V winding.

Hammond 290BX (120V) and 290BEX (240V) are electrically OK but I have no idea how M-B mounts it. 290EEX would work but may be too large.
