I have the 89B 123 with the 77 detector. I had to rewind the oscillator coil as in many other sets and all is working and about to package it up and call it fixed when lo and behold I find a parasitic. The set is self oscillation on 600 khz and there is a station in this market on that channel. So out come the bypass cap and see if I can place it across something that will stop the parasitic. Just wonder if any others have seen this.

Maybe a few drops of Frontline or Advantage, take care of those nasty critters.

yea buddy, if you have ever spent a night in a cold transmitter building trying to get birdies out of a broadcast transmitter, now that is some fun!!! Napalm might work better.

89B is 34 Tombstone, I had birdies in the first RF Amp-1st Detector/Mixer, just backed the gain down a bit.

Methinks you mean a model 19. Well you could have taken it to France to be with all to other Parisasites.
