I think I finally made it. OT ham, early 60's ex-K9ZSL. Going for retread. Salvaged local radio station where I put in about 16 years over 4 stints. Found choice iron. Must have been custom jobs, perhaps for early Gates 250 series. The station was exclusively Gates at least until 1964 when I left the first time to attend the UW Madison. Numbers are: Mod xfmr T-4M51; Reactor T-8C82. What are these thingies? Can also reply to
passagerecording@yahoo.com handle is Mike. Clear.
