Thanks Chuck for the info on Swan. My dad bought me a 350 new in 1965
when I was 15 years old. Loved the radio even tho it did drift. I have
one now and am having a blast working on it to modify and improve the
drift problem that they all had.

Swan's answer to the drift problem on the later 350's was to put
the transistor for the VFO (2n706) in a small box mounted under the
chassis. They figured that that would keep it isolated from the tube
heat. The best answer I have found is to turn the radio on at least
one hour before using. That is easily done, as it often takes an hour
of tuning around the bands before you are ready to start transmitting
anyway.
