[NSRCA-discussion] Kraft info

[Bob Richards]

IIRC, Hobby Lobby sold a radio that was actually made by EK Logictrol. The servo amp was not in the servo, it was in the receiver (it was a big receiver). I think the servo direction could be changed by rewiring the connector or by reversing the connector - can't remember for sure. Anyone remember that? This would have been in the early 70s.
