10KV caps.

Your case is a slow replace this or that and fire it up , interesting way to do it but from what I see in the pics a full recapp and it probably will be good to go.

When I restore anything more complicated than an AM radio, I first get it running to verify if the "hard" parts are good or not. If it had a dead CRT (which was actually expected since it had a brightener installed at some time in the 1960s), or a bad flyback, or a bad yoke, or a bad power transformer, I'd abandon the project and move on to something else, particularly with a rare bird like this Andrea. If it was a common TV like a 630, I might be inclined to shotgun it and deal with a bad transformer or yoke if I came across it.

Ordinarily, I would indeed just recap the Andrea at this point now that the hard parts are verified to be working, but I wanted to use some tube troubleshooting skills that I last used (at least with television) in the 1970s or early 80s at the latest. If I was restoring this for a customer (I've done a few), I would have shotgunned it. But there is a big thrill in getting it going bit by bit. It was fun seeing the tube light in the first pic, then another thrill at each step, and I was smiling ear to ear when I got the first picture on it.

So instead of shotgunning the old girl, I'm working through it. Once it's running 100%, I'll go ahead and restuff the remaining cans (I think there's four more cans) and replace the balance of paper caps.

BTW, I like restuffing the cans because I hate adding terminal strips and external caps underneath the deck. If someone in another 70 years works on this TV again, the bottom layout will still look like the pictures in the Photofact. So it's not for originality, it's for keeping things neat and recognizable for the next guy. Hopefully, this TV will be running long after I'm gone (to the Carolinas hopefully ).

Working on the various circuits instead of shotgunning is like building a model: I can't tell you how much I'm enjoying each step, and will be a bit sad when it's finally over.
