RCA 36X

Picked this up at an Arizona Antique Radio Club swap meet. Many of the radios there were priced a bit high but this one was reasonable and had been completely restored.

 It had one major problem, it didn't pick up anything but static and crackled when the tuning knob was moved.

I found that the plates in the tuning capacitor were either slightly corroded, touching, or had tin whiskers. I carefully cleaned the plates with fine grit sand paper, and now it works perfectly. This is now the oldest radio I own circa 1941.
