I've been working on slowly getting my Capehart back together. i
Thought I had replaced all the wax caps. NOPE!
Brought up the set nice and slow. I heard the sound come up, then i started hearing sizzling. I killed the power promptly and turned the chassis on its side.
I could smell that nasty hot smell, you know --the one just before catastrophic failure!
I looked around, and behind the Horizontal hold coil (which was shielded by a can) i found my two culprits. One was still bubbling! The other was slimy and had started to melt.
A little longer and their could have been a bang and a big nasty mess.
Always replace those old caps and double check your work
