Hi folks.

I'm new to the board, my name is Patrick. I'm a career RF/systems engineer.
Greetings all around!

I just made a couple of 'good' handyman special buys on the worlds largest
auction. I got a PRS10 that needed a new SA612A mixer that I got working,
so, happy about that. Thanks to KO4BB for having the schematics.

I also picked up a FTS4040A, apparently with a failed PSU. Its labelled
'high voltage' , but the dinky 24? 26? Ga output leads (red/black 3x
ganged) don't led me to believe that there' s 2.2kV here. Can any one shed
some light on what this PSUs output is? I'm hoping that I can either fix or
replace it and find a diamond here.

Thanks for your help.

Pat
I am familiar with the fts4050. Please send me a pix of what you are
looking at. Best to do this offline.
Thanks Paul.

Patrick,

Nice find on the PRS10 and Datum/FTS 4040. The cesium is definitely
worth trying to get working. See if either of these pages help:

http://leapsecond.com/museum/fts4040/

http://leapsecond.com/museum/fts-7504/

The thin red / black wires you speak of are the +24 VDC and +10 VDC
power into the HV modules. The actual HV output comes out of those
special (black & green, or pink) highly insulated connectors. Let us
know if your 4040A looks anything like what you see in my photos.

If anyone on the list has experience with rodents, you'll notice the 4th
photo of the fts4040 link above shows that a mouse nibbled on the pink
silicone insulation around the HV connections. So be careful where you
store your old cesium standards. I'm used to bugs in s/w but rats in h/w
is a new low. What kind of HV goo should I replace it with?
