The keyer, as expected – in great condition, however, I will recap it and also test the tubes.
And, look what followed me home:
The surprise? A Central Electronics MM-2 “Multiphase RF Analyzer” – which is a 3″ CRT based oscilloscope. This model has the capability of monitoring both the KWS-1 transmitters waveforms as well as the 75A-4 received signals.
The gray Vobroplex Bug, this TO Keyer and this MM-2 were all sold in 1960-ish, so they are the same vintage and about 5 years “younger” than the Gold Dust Twins.
More classic gear from the Gold Dust Twins “era”, and more fun in the KY6R shack!
