Well, I finally got my tombstone!
#10

Good luck, Jake. By the way, don't let some folks here fool you about electrolytics. You CAN go OVER in capacity by as much as double, I have with no ill effects, but up to 50% is more like it, say, using a 30MFD for a 20MFD, or a 22MFD for a 20MFD, but only if you have to. I always go OVER in voltage, using 600 volt continuous rating, even if the original was 450 volt. NEVER go lower in either capacity or voltage rating on filter condensers. Also, be careful about the polarity. One of the originals has an insulating fiber around the can, with a tab connection that isolates the can. It filters the negative bias voltages, and is important to hook up correctly.
