[Boatanchors] Electrotone M-100 modulator

Tue, 30 Dec 2003 16:21:58 -0500

Despite my best efforts at maintaining a neat and orderly collection of
manuals and assorted other gear related paper-work, one item...which I
know that I have...has disappeared into the mountain of BAMA material.
Or possibly I put it somewhere else to avoid it getting lost in the BAMA
stuff.  In any case, I am desperately looking for the instruction sheets
for a screen modulator Model M-100 manufactured back in the '60s by
Electrotone Laboratories.  It was described as a "series gate modulator"
and I successfully used it many years ago to get several hundred watts
of low level AM out of a Viking Thunderbolt.  Sort of a DX-60 on
steroids.  Can anyone help with copies of this documentation.  I would
happily pay for any duplication and postage costs involved.
Thanks very much and best wishes to all on the list for 2004.
73,
Ken K4XL
