Substitute "CN12" for "VR1" and things should be clearer. The regular
tuning is done with the switch AWAY from the connector.

Well, to C of course. Just connect a regular (electronic) tuner to the
output of the Polysix and observe it. Alternatively you can connect your
scope to the "SIG OUT" test point (TP1).
