Still Having RCA 8TS30 Issues

A 12K rated for 3 watt or better will do. If you don't have one handy, use a 10K just to see what effect it has.

Here's how I did a 721TS recently. I paralleled a 1500 with 5000 to get the required 1125.

How common is it for the larger 25w resistors to be bad? The tested OK on mine a few years ago, so I left them in. only 1 section candohm resistor tested funny at the time, which I bypassed, I should have done all 3 sections, as I now suspect the other 2 are starting to fail as well, as when the sound is at max,the picture shrinks horizontally. Granted this set had no sound OEM, but that sound not be an issue, as it has the same power system in it as TVs with sound originally.



For now, I have the audio output pulled and am using a cheap LM386 amp for sound till I address the candohm resistor issue, but, do I replace ALL the bleeder network preemptively, or leave the larger 25w resister in if it still seems good?
