All paper caps both LV and HV have been replaced along with all the resistors, and all the e-caps too. The only thing done to the tuner was to clean the wafer switches.
Here is a very short video of my biggest problem right now. The picture goes negative when I turn up the brightness. I substituted the miniature tubes along with the 6V6 HV Osc. tube. I don't have 1B3GT tube or any of the Loctals. A club member thinks its the CRT and to prevent it it needs a brightener. BTW my HV is still low at about 4Kv instead of 5Kv.
Any ideas of what to do?
