[sdiy] old man help

[Robert Weigel]

Hey Greg,

I have my information on the specific impedences at home..but if it's out
of something with an op amp driver...usually the most common primary
impedence DC should be 57 ohms or close to it.  Output should measure 210
ohms or thereabouts.  Common problems...wires breaking between the rca
jack and the coil's connection...and on newer units mfg in mexico....the
fine coil wire forming a bad connection where it terminates at the pins
that the connector attaches to on the coil.  Apparently..they didn't
properly strip the enamel off the wires on a whole bunch of them.  Tons of
them failed in Fender Amps and others.  Take care, -Bob
