41-250 Restoration
#18

Thanks. I was having a time figuring out the tube diagram.

For some reason this person connected a cap to the 41 tube. Plus two 20 mfd caps - one connected directly up to the bakelight block. I’m not sure how this even was working. And two 20 mfd caps in series.

I’ve got an 8, 12, and 16 mfd cap on order so I can make this all correct. Parts 27 - an 8-16 dual cap and 62 on the parts list - 12 mfd

Probably too much detail but for the benefit of others -

The lesson here is that working doesn’t mean right. The second lesson is put in a fuse.
I did that when I got this. Third lesson - don’t trust other people’s work

Clearly the radio was powering up so it’s fundamentally sound. My thought is that some of that crumbling wiring just shorted out.
