Hi -
I'm in the process of refreshing an SX-636 and came across a cap value discrepancy on the power supply board. C-12 on board AWR-060 B is 10uf 16v but it's listed on the schematic and the BOM list as 220uf. I don't see a service supplement for this particular receiver, was this a production line change or a previous tech's error? Serial number is VA3927xxxx (January of '75, fairly late model I guess) and it has been working just fine with the 10uf cap in there. I replaced it with a 10uf 50v UPW but I've got 220's on hand too. It looks like it's been in there from day one, no glue ring or signs of a larger 220uF cap on the board. Whaddya think?
Add-on: The power supply board also has AU LX stamped on it if that makes any difference.
