Hello all. I'm restoring an old radio, and in the process of replacing
the assorted electrolytic caps, I came across a half melted looking wax
coated cylindrical cap. The only markings on it are "Micamold 420E2503. On
the next line, it says ".05 plus or minus 20 150". It's a tubular shape, not
the usual postage stamp or lozenge shape that Micamold caps usually are.
It's got a band on one end, so I'm guessing it's polarized - although the
end without the band is grounded, the opposite of what I would have guessed.
I'm guessing, .05MFD, 150 volts. I can't just look it up in the schematic,
since this this part of the radio is a circuit a previous owner added on to
support a Magic Eye tuning indicator tube. What do you think?
