I'm buying parts for a XO upgrade for SDA 1a and I can't find a 13uf cap on parts-express for solen or dayton. Any ideas?

Use two caps in parallel that equal your goal uf wise. Try to find two with similar value.

BTW I do not see any 13uf caps in the earlier SDA's. I would double check to make sure that it is not a 12uf.

Should I use 2x 6.2 or 2x 6.8? I think these are my only options.

The parts list says 13uf in the 1A's. I looked in the cabinet and the dimensional board has a yellow cap that is a little smaller than the yellow cap on the stereo board, which I think must be 13uf.

I am almost positive the cap in question is 12uf. Polk did not use any 13uf caps(13.5uf) till much later.

DO you think the parts list in the DIY section is incorrect then? I will try to take a pic of them right now.

I'm in Youngstown , OH. The schematic says 12uf but the parts list says 13uf Hopefully you can see what im talking about with the different sizes in this picture.

Use a 12uf and be happy:) the Stock caps are 20% in most cases.
