Keep an eye on transistors leads, they can also rust and fall apart. I got a Cobra 138xlr here that had a bunch of transistors with the leads rusted off.
Thanks for your suggestion. The 520 has been running well since I replaced the capacitors but I will certainly open it back up and take a look at the carbon resistors.
Picked up a used 520. I have output on cw but not on ssb. Still checking microphone, and will check capacitors. Do you have any suggestions? Thank you!

Thanks for the tip, I'll keep an eye out for that.
Corrosion from humidity, check the big one watt carbon resistors on the PA board .

Read all of K4EAA stuff, shame he passed! He was the Kenwood Hybrid expert. JohnBoyUtah KJ7TBR
