[time-nuts] Racal Dana 9478 frequency distribution system with option 04B high stability oven (5x10^-10/day aging rate).

FWIW it is trivial to modify these video distribution amps for 50 ohm output - you just need to change the output resistors form 75 ohm to 50 ohm on the board after the op-amp.

I want a distribution amplifier to distribute 10 MHz from an HP GPS
 :
Currently I am using 75 ohm video amplifiers, but I suspect that is sub
optimal.
