[R-390] Nixie Tube Freq Readout

[Robert Harding]

Try a "Systron Donner" Model 6152A Frequency Counter. Has lots of other uses around the shack and uses bright Nixie tubes. 

Used in the late '60s to mid '80s, these counters are military/cal lab grade and can be found in decent shape for $50-$150.
