Default Re: Marconi NS702 / 2207E, SN 623 (Atalanta type) receiver

The 700kHz rejector is a parallel tuned job and it's in series with the primary of the RF coil that's connected to the anode of the 1st RF, it's connected between the "cold" end of the primary and HT, those two windings in series as a whole have a 680 ohm connected across the whole between the anode and HT, so far as I can make out.
