Well, I'm making progress as of today but I still don't get what's going on. I replaced the shorted electrolytic cap, and since my capacitors should all be good now, I went about replacing a few resistors. Found a couple that were way off. I have four variants of the 6X5 tube; the first type with two rows of plates, the second and slightly smaller GT version, the X-plate GT version, and the military spec Raytheon WGT. I've been testing using GT, and I'll be leaning towards the X-plates for longer periods of use. No problems there.
I've install a Y2 line filter cap and that dulled down a lot of the buzz I was getting before. Now I only get a soft buzz when the volume is all the way up, just like on a cranked guitar amp. No noticeable hum, but there is static that comes through the speaker intermittently. I get it when I turn the volume and tone dials. I had it switched to phono earlier and could still hear the crackling here and there, even if I don't touch the tone dial. Not sure what's up with it now but I haven't picked up any radio stations on Shortwave or Broadcast.
I'm debating on where to turn next. I'd like to test it with an MP3 player connected to the phono input. There's a brown and a black wires coming from the cartridge which go to a terminal. The brown side has a ground coming off of it to the chassis of the record player itself, and the brown and black wires go together in a cord running to the plug that connects to the radio's chassis. I have some headphone wires with an appropriate plug for the MP3, but I'm not quite sure how I should go about connecting between the record player and my radio.
