Unplug your radio. It's humming that song "My Electrolytic capacitors, ain't no good". Their shown on the schematic of the 780x to the right of the 5y4G rectifier that's in your mailbox. Those caps 20uf/450v,15uf/400v,8uf/400v and the 20mfd/25v have to be replaced for starters.After that you can move on to the paper/wax caps. You might want to check out a primer on cap replacement on the Just Radio site.

BTW your radio was made in 1939.

Hi Mike - I used to own one of those and have fixed several more just like it - I'm not sure from your post - were you able to get it going ? They are good radios with beautiful veneer in the cabinets - but not difficult to repair - let me know if you need anything - I think I have factory schematics on that one.
I havent had a chance to get to it. I am in the midst of getting all spare parts for it. Something that would be nice is an owners manual to replace the one that is missing from the envalope. If you have one that can be copied that would be nice :P.

I am in the midst of getting all spare parts for it I don't dare take it outta the crate right now until i have everything ready. hmmmmmm what do you think a westinghouse crate would go for **just kidding** Something that would be nice is an owners manual to replace the one that is missing from the envalope.

Factory schematics would be nice to.
