Ok, I have some good news. I got the AC line supression capacitor and the two 47 ohm inrush thermisters I connected in series to get 94 ohms. The set doesn't vibrate anymore or seem to draw insane amounts of current. I installed the .047uF 275V X2 AC line supression cap across the AC line like it said in the Sams/RCA service guide. I installed the two inrush thermisters in series across the AC line. They have a cold resistance of 47 ohm and a current capacity of 3A. That should give 94 ohms of cold resistance with plenty of current capacity at 3A.
The 160uF/50uF/50uF multicap gets warm and stays warm, but after being on about 15 minutes, it just warm. It's definately going to have to be changed, no? I'm just testing for sound, as it's not connected to the picture tube or yoke, and the horizontal oscillator and output tubes are removed. It's tuned to channel 3 and connected to the RF out of my tivo. I'm getting sound as clear as a whistle.
As for what was causing the vibration before, I have no idea. The AC line filter which includes the AC line supression cap connected across the AC line and the 820k resistors that are connected to ground and the two sides of AC, maybe that was causing it since the capacitor was removed? But with 820k on the 110V AC line, only microamps flowe from AC line to ground through the resistors. The thermisters? I have no idea if the absence of those was any big deal. As soon as I get some screws and nuts I'll install terminals and remove the multicap that gets warm. I'll install the new ones on the terminals. Then I'll connect it to the picture tube and see what happens.
Thanks guys.
