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

[Dave M]

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.
