So I'm in the final stages of restoration now!
Okay, to be fair, it was mostly restored already. Anywho.....
I have one filter cap to do. It's a double 70 uF @ 175V. Weird thing is that there are no polarities marked on the cap, 4 wires, two of which go to ground.
I would normally assume the negative leads are chassis ground, and the positives go to wherever they go, because it's not labeled as a bias cap in the Sams. But, on the chassis ground side of the caps, it almost looks like a "+" scrawled into the solder. I've never seen a filter cap with NO polarity markings on it whatsoever, and 4 wires coming out of the cap, two on each end.
That said...what way does the replacement go in?
