I got the HV rect tube today, odd that the new one has a flashed getter and the old one does not, HV is still quite low, As i suspected, the HOT is also bad. has blue glow ( not as bright as the old HV rect was), will most likely also replace damper with solid state, only $10, and will never go bad. ( i hope )

very likely have other weak /bad tubes. for when i feed video into 1st vdo amp, by the time it gets to the final video output it looks like crap, noisy and distorted. and since in this set, the sync is taken from the final vdo amp, its very hard to get lock in this situation.
I should also go and check every resistor in the video line now, something I did not do yet, I was HOPING they would be OK enough, foolish i guess for a 70+ year old TV, i guess that it's working as well as it is now is a sign that they are SORT of OK, but that won't be good enough to get clean video through it.
I only worry about the filter coils that are wrapped on resistors, I have no way to test or replace them if bad.
on one up note, I WAS able to tune in something, but it was VERY unstable, and i could lock in on better sound,or better picture, and to see video i hooked up a ext color monitor to output of the video det (v8a SAMS) junc of L18&L19 through a .05 cap and was able to see a pic if i tuned it JUST RIGHT, ( very hard to get it ), i even got color through it, which i did NOT expect to see.
