Just wanted to say thanks to all for this great info. My v1.B went bad, and I ordered the parts from Digikey. Just installed them, and bam, a working 2413S.
I ended up going with a Rubycon cap for C7 & C13. It is a smaller design for the 100UF 50v, which enabled me to install them upright. There were stated to be long life 10,000hour power supply caps. The part number is: 50ZLJ100MT78X11.5
Thanks again!!
