Help Pse: DSI 5600a freq Counter

[Mike W]

Hi Folks, I have a need for the circuit diagram of the crystal
timebase oscillator for the DSI 5600A frequency counter. I have
diagrams of the main board and the display board but, as Murphys law
states, the fault is in the bit I don't have the diagrams for. Any
help appreciated.
Thanks, Mike G8NXD

Can we assume you've contacted the manufacturer?

Hi Mike,
Good luck. I just pulled out my manual, it's an original, and like
you say, there's no info at all on the 10mc timebase ossc. exc. that it's
"ovenized" and takes 9vdc & (I think) 5vdc inputs, and puts out 10mc. I
got mine used at a hamfest probably 15 yrs ago, it was built as a kit,
looking at the marks in the manual. It's worked for me since, after I did
something (can't remember what) in repair.

Not Yet. I did'nt know who was the owner of the design these days,
Thankyou
