In Reply to: RE: Recapping receiver - slow progress and and couple questions. posted by DRam on January 31, 2017 at 21:02:42
I have come across a few instances where the + symbol silk screened on the board was not the + pin on the cap that was installed. I did not have a schematic, so I dont know which was in error. Since the unit worked fine for years before I got it, I installed the replacement the same as the one I took out, even though the board showed otherwise. So far so good, no problems. I always take a marker and make a mark on top of the old caps before I remove them. I make it on the side toward the front of the unit, so after removal, I know what orientation it was in. It has come in handy a few times.
Follow Ups:
Once again, use a marking pen and mark the BOARD!!!! BEFORE !!!! you take that cap out. If there is a discrepancy between the board and schematic - go with what's already in there.
I got into the habit of marking the negative leg.
The cap with the arrow sign is a variable capacitor. Don't touch it.
