crosley 515

Am trying to bring back a crosley 515,found some caps I havnt seen before 8-450 and a 6-450 dont see any polorazation to tell me they are electrolytics,can anyone help.
Thanks,Clay

Hi Clay,
Yes those are electrolytics - items 6Y & 6Z on the schematic. The positive ends are tied to the chassis. You can replace both with 10mf 450v caps.

I Should mention that there are a couple of 2 section caps in this chassis with 1 wire in each end and a strap to ground in the center (7Y & 7Z, 8Y & 8Z, 10Y & 10Z) these can be replaced with individual caps.

Missed 11y & 11z.

Clay: looks like those 2 are in one can from the schematic (http://www.nostalgiaair.org/PagesByModel/373/M0003373.pdf). You can use electrolytics there. You might want to use 10 mfd for better filtering. The 6Z designation on the schematic for the 8 mfd cap, the positive end goes to the rectifier cathode, and the negative to the common negative (heavy line) which is B-. The 6Y cap negative goes to common negative B-, and the positive to the B+ line.

I went back and read my first post - I can't believe that I got the polarity backwards.

Yea, I think that schematic with the tube diagrams upside down and all the filament wirings had us all doing a double-take.
