RCA-76 cap question
#2

Quote:I have the pos of 36 tied to the pos of 35 and the red lead tied there going to L3 and the neg of c35 going to the resistor block is this right?

Maybe we're looking at different schematics but I don't see where you came up with L3. The + side of C35 & 36 goes to more than one place, and that includes one side of L16, L19, & L7, but I'm not sure how you came up with L3.

OK, I think I see what the problem is. I'm looking at the schematic and you're looking at the wiring diagram. In the wiring diagram it does look like red is going off to L3 (I think, but it is hard to read), probably as a tie point before it goes off to the other points. The same with black/red going to the resistor block, also as a tie point. So yes, your original assumption seems correct.

What you want to do is use both the wiring diagram and the schematic together. Actually measure with an ohm meter that each tie point is going to all the places it is supposed to. That is just-in-case you have accidentally removed or mis-routed a wire.

I also like to check this before removing components to make sure the factory didn't change something without updating the schematic. That, of course, is in the rare instance that a wiring diagram even exists. Seems like RCA and GE were better about doing this than most manufacturers.
