The alignment instructions on this 53-1750 call for the hot (center) side of the RF out cable from the signal generator to be connected to pin 6 of the 7A8 tube and the grounded part of the cable (shield lead) to be connected to B- in the radio. Is B- just the same as the metal radio chassis? Also, in addition to plugging the radio into an isolation transformer, should I plug the signal generator into the isolation transformer as well? Thnx.
