[time-nuts] Need sevice manual or schematics for Fluke 103A

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
