re: The 37-650 Saga

I just pulled the 2nd IF coil can for a look-see, and
to clean up the trimmers, in case they are dirty.

While doing so, I took the following readings:
(#28 on the schematic, for those following the
proceedings here)
Readings made with all wires disconnected from
trimmers: trimmer number given for coil reference
only, ohmed circuit is the coil shown for each
trimmer. I made sure to clean ends of coil leads, in
case they had varnish, rosin, etc., throwing reading
off.

Trimmer 28P coil should have 12 ohms resistance. Reads
14 ohms

Trimmer 28S coil should read 8 ohms total, and 4 ohms
at tap. Actually reads 14 ohms total, with 10 ohms at
tap.

These sound high to me.

How may these readings be contributing to the
misery...er, mystery...
