Hmm, looks like E/W Pincushion doesn't have any active components in the
circuit.....but I don't see how they inject a pin correction signal  if they
don't. Of course, RCA utilizes a circuit consisting of only a diode, a cap
and a transformer.....I don't see why Memorex can't do the same. Good luck
on that, hope it's only the coil.
