WOW! That is really great information! The picture of the actual Cabinet Dipole is really helpful ( I think 28" is half wavelength for the nominal freq). I have just spent the past day tracing connections and components. I have designated Terminal Lug numbers and on the prints - I'm having to label every connection, just so I don't miss anything. The guy that worked on this unit before really did some changes. He added two terminal lug strips and rerouted and added a number of components. One strip went to an RC circuit hooked in where the ground should be on Z301 - so it did not have a true chassis ground on the secondary winding. I have no idea what he was doing. Another 0.01 uF cap, 1000V was added but he ran both ends of the cap to chassis ground (???). I think there was noise and he tried to design a filter on the 2nd IF Amp. It has been a painful task of redrawing component layouts and then tracing them point by point on the actual schematics. It is fun but very challenging. On a separate note - I just finished working on a 46-1226 ( my hobby). I had poor reception on SW (bad tuning cap - replaced) and there was a lot of noise on AM. I made my own tube extender (breakout box) for the 7AF7 to access tube waveforms. I took many scope pictures and used ChatGPT to create me a troubleshooting document. It clearly shows noise, that ended up being poor connections on the IF Amps. That AI really helped a lot to build the document (30 pages) Should I create another chat to post that? It may be helpful for someone else.
