Yes, the 103A is the Frequency Comparator; the 203A is the Distribution Amp.
Sorry for the mistake.
The 103A manual price as listed, is $25 plus shipping. I received
confirmation this morning that is indeed the Montronics Frequency Comparator
manual with schematics, so I ordered it immediately
(http://www.manualsplus.com). Don't know how many they have in stock.

The Fluke 203A is the 1 MHz Distribution Amplifier
What's the 103A manual worth ?

Thanks for that, Phil. I have located a listing for a Fluke 203A
manual,
but don't know yet if it's for the Fluke/Montronics Frequency Comparator
or something else from Fluke before they acquired Montronics. Waiting
for
a reply from the vendor. If it's the right manual, I'll buy it rather
than bothering with scanning/copying.
I have not isolated the trouble.. without so much as a block diagram of
the innards, it's a bit difficult to get much figured out without making
it a summer-long project. The trouble is that the front panel phase
meter
and the phase output jump around quite a bit, even when feeding the same
source into both inputs. It's like it can't figure out which frequencies
to mix for the comparison.
In a different vein, I also have a Fluke/Montronics model 203A
Distribution Amp.that I'd like to get into. It's set up for 100KHz, 1MHz
and 5MHz channels; all non-isolated. I'd like to see the schematics for
the preamps and output amps so that perhaps I could modify the 100KHz or
5MHz channel to be a 10MHz channel, and provide isolation as well. Can
anyone help with the schematics for the 203A DA?
Thanks again, Phil; I'll be in touch if the manual turns out to be the
wrong one.
