Model 89-123
#1

Hello! Iam having a problem reading the most recent drawing of the 89-123, showing the 77 tube osc, as mine has a 36 tube as well as a combined on-off wave band switch. I have a resistor that is completely burnt, and canot make out its value. I have the service bulletins prior to the change to the 77 tube, but this confusses me even more! Is there a schematic out there, showing the 36 tube as well as the on-off wave band switch, before the 77 tube was implemented.If anyone can help me,it would be very apreciated.Thank You
