Also if the damper tube is bad there is no way in hell you'll get HV out of it.

Expect to replace some lytics, the paper caps in the horizontal section and any paper caps on the B+ boost line that the flyback supplies before HV materializes.

Thanks guys, I replaced the damper tube, and plugged in the speaker. Got a raster! It actually looks... not too bad given that it's all original (minus the filter caps). It lost it for a minute though, not really a big surprise, but it came back. I hadn't changed the damper tube because I thought I didn't have one! My dead-project RCA Victor tv DID have one though. Also the tube is surprisingly bright for testing 'bad.' Even in my brightly lit room, you could probably watch a show no problem.

brb recapping.
