But the origininal poster's rig... that 200 ohm number doesn't sound good
to me. Put 6VAC 60 Hz into the primary and measure the ratios... if there
is a shorted turn, the DC measurements may change a little or a lot, but
the AC measurements will be totally off. On the other hand, you may have
a different transformer than was original; if so the DC measurements will
be completely off but the AC numbers will be fine.

Hi Scott. Yes, I'm suspicious of that 200 ohm number too but have
decided to leave it in for now and carefully see what happens. Your idea
sounds good and I may give it a try. Can actually check it at ~1 kHz too
with an AF generator.
