  • mystery amp

    I would like some help identifying this amp. It was brought in by a local lap steel player for a basic service and updating to a grounded power cord. There was a small paper label on the main chassis with the model number "50 W RT". My guess would be 50 watts with reverb and tremolo. Tubes are: 12ax7 x 5, 6u10, 5u4, and 6l6 x 2. This amp looks to be very carefully hand built, all point to point between sockets and terminal strips, with a very neat layout.
    One of you out there must have seen one of these before, or may be familiar with this maker. Any info would be greatly appreciated.
    Thanks, ...Jon

    It's a Sano. Somebody has changed the badge on it.

    "Enzo, I see that you replied parasitic oscillations. Is that a hypothesis? Or is that your amazing metal band I should check out?"

      Thanks to Steve's lead, I found the answer to my question.
      JG is Julio Giulietti, and this is an accordion amp, with a special stereo accordion input. Made by Sano, model 50WRT.
      I also found the schematic at the Duncan amps site.
