well every other can cap tested fine, oh well nver hurts to check. I have checked all the brightness stuff since the CRT was a bit dim, all looks good. So to recap no pun intended,

200mfd 50v cap on video amp tube.

1.5 meg resistor on shunt tube.

I cleaned up the pot controls, including the on off volume that was inside the uhf knob it was sticky.

I sure hope there is no diddliing needed, the coil forms have what looks like dried cheese in them, my guess is the forms have started to break down.

I will put it all back together tomorrow, set it on the variac (to keep the HOT current low, use 110v ac line) and do a complete setup.

hmm the only thing I did not check was some of the caps on the convergence board, there was a bumble bee in there as well as one of white tube caps. I will check that out as well, my guess is the bumble bee will be leaky.

Anyone have exp with the yokes with the fishing line coming out of them? from what I read there are for centering the pic, but I have never had a set with them.
