I'm working in a Stewart Werner Spade radio. I did a recap job and i replaced the 8-8 mfd at 350 cap with 2 10 mfd caps and now I still get some 60 cycle buzz in the speaker. I did check the caps and they did test out good. Any ideas?

Check 18A 18B 18C resistors. those could have gone way up in value. Do check over your new capacitor connections. Positive sides join together, One negative side is ground, the other negative goes to field coil, and center tap of power transformer.

Yes check resistors...as stated..also be aware that if you have any dimmer switches in your house they will also put out a buzz when turned on...as will appliances and other items...

It is common for most radios to hum just a little. Some bad designs hum a bit more (especially some AC/DC sets at low volume). Some good designs (such as my Philco 60) don't hum at all. My Crosley 1117 hums a bit more than I'd like it to, but there's a whole strew of problems linked to that (such as massive hum being picked up by the unshielded 1st audio tube...and I hate to put a metal one in its place). Seems, though, that as designed, the radio just naturally hums more, even when the 1st audio tube is properly shielded.

:It is possible to buy electrical dimmer switches with RFI suppression and they work quite well.The reason I know this is that one day I bought a dimmer switch that affected the radio when the other dimmer switches in my home didn't. After a little reading, I found out that switch wasn't protected. The ones with RFI suppression were only a couple bucks more.
