Vintage 1930s Rickenbacher Electro tube guitar amp. Amp uses a 6J5, 6N7, two 6V6 and 5U4 vacuum tubes. Amp has had the filter caps and bypass caps replaced. Comes with vintage tubes. Amp does not appear to have any modifications and comes with a Utah field coil speaker that is likely to be original. Has the original tone and volume pots. Tone pot works, but is hard to turn. Since it is original it was left as-is, but fully functional. It is in good cosmetic shape for its age and sounds great. Professionally serviced by Amphole in Los Angeles.
