Subject: [alt-beam] Re: capacitors
you want 224 on the caps. The third number tells you
where the decimal is, I think. I would have to check
on that. I just look for 224 now. Tech America has a
great catalog that explains the ceramic code. Try a
Rat Shack for the catalog. I wouldn't full aroound
with the 2.2k resisotr much. It affects the latching
of the SE.
