Were the original box caps actually micas, or papers that looked like micas? Is there a way to tell? I have a 51 Andrea with a bunch of the beige "micas" that look like those in your TV and I'm not sure if they actually are mica or not.

Good rule of thumb is to check the rated capacitance... usually everything below .001uF=1000pF (or mmf if you prefer the old notation) is genuine mica and everything .0047 and up is paper. I typically replace every rectangular cap .001uF and above with film caps. Even true micas are prone to failure in sweep circuits so ordering spares for those for the sake of our mutual friend Justin Case is an advisable measure to take.

Thanks Tom.

More progress.

I did V3, V4, V5 the IF tubes, V7 the Video Amp, V17 the Vertical Multivibrator, and V18 the Vertical Output tube.

I decided to use the "coil" method on the 7 and 9 pin tube sockets. I didn't want to damage them. I did completely remove the component from the 8 pin tube sockets and terminal strips.

This evening I finished the recap.

I then replaced all the tubes and used my variac to power it up while monitoring B+ and current draw.

I got a picture and some faint audio. I haven't done a thing to the tuner and that will be next. Very flaky.

Here are some pictures of the completed underside and a picture of the CRT picture.

Getting there.

No, I think that's the way Jack Klugman looks...

Wow, unbelievably neat work.

I'm actually surprised it's not performing better given all the new parts installed. The good news the tube looks fairly strong.
