  • Notes

  • The Sonora 33 is an AC operated 6 tube BC band receiver. The switch on the side of the radio is the ON/OFF power switch.

    The tube sockets are labeled for the 71 tubes, but there are no markings on the 36 tube sockets and so the 36 tube may not be the original type tubes (Maybe 24's??).
