Hmmm.
I bought capacitors from Radio Shack. They look exactly like the ones in the pics from pelked.
They say:
220uF
Electrolytic Capacitor
Axial leads
35WVDC maximum
Thank you guys.
EDIT - I see that there is a post with the capacitors I bought that says 'Do not use these.' Guess I missed that in the 149 posts. I'll order a couple from Amazon.com.
