I restuffed all caps but the tin can, but delaying replacing them as there more work needs to be done under where they go.
First of, I need to clean the mushed wire insulation stuck to the chassis and things in it.
THis is how it looks. I do not think this was an animal activity, as there is no droppings and such, but also this is only near the candohm, which was supposed to be hot as heck. As I said, this will be replaced by a capacitor, and it just so happend I have exactly the value, 8.2uF film Solen caps (8.3uF was the calculated one). I stocked up on thos a few years ago as this seems to be the one often needed to replace the curtain burner wire or a candohm in these 5-tubers.
I also figured why the choke 32-7569 was burnt (and replaced by a large ceramic 2.2K resistance): the catalog gives this as a 10mA choke, and the calculated curren through it might be up to 12.8mA (and I am sure it was at least 10mA), so it would be used at its limits.
I want to reinstate the choke, so I will be buying one. Not necessarily the exact replacement, but I'd like it to be at least around 20H and a 1.5K or so, the rest will be compensated by an added resistance.
This radio is a handful.
PS. I was told "if you plug it, it will play". Not sure, but then the cord was cut.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
