[time-nuts] 10544 TCXO used in H/P 5245L counter

[D. B. Collie jnr]

I`m looking for a pdf of the schematic of the motherboard that the 10544 frequency reference plugs onto in the H/P 5245L counter. This is the one that has a 723N, and a 7490N to produce a 100KHz reference. Something is amiss with this board. Thankyou.........................................Don.
