Wow! They sure knew how to cram things in with this model? I'd imagine there would be quite a bit of heat generated when its running. And that short necked shallow CRT....it looks wrong!
I've been following your videos on this and amazing how many tubes you found that were bad and yet the CRT is good.
I recently did up a TV to use in the workshop which had being lying dormant for years and half of the tubes in it were also weak or bad but this set has had very little use due to the lack of discoloration on the circuit boards and certain electrolytics that usually fail were still ok and virtually no dry joints on the tube sockets so go figure on that one?
Just another strange aspect of old electronics....
And those silicon diodes...they are weird.... look like caps!
