Hi all,
I spent some time today cleaning and preping my 650B chassis for the electronic restoration to come. I removed the tuning gang and cleaned and greased it. I also replaced the mounting grommets. Boy, removing that tuning gang is not a job I would care to do again on the 650B. I ended up having to loosen the band switch mounts and push it backward to get to the rear tuning gang bolt. I unsoldered the ground braids on each gang on the chassis top at the capacitor. The middle and rear stator wires were most easily unsoldered at the bandswitch. The front stator wire was most easily removed atop the chassis at the stator terminal itself. What a lot of gyrations to get this done. It is definitely not one of the easier tuner gangs to remove.
Anyway, since I had the gang removed, I went ahead and cleaned and polished the chassis while I was at it. Whew, this chassis was really dirty and greasy and grimy. I swear this chassis must have spent most of its life stored on top of an oil burner. Well anyway, I guess I'm ready to start the re-capping now. Here are a few pics of my progress.
This is the chassis before any work was done.

Oh yes, I forgot to mention, I slapped a coat of paint on the transformers too.
