  • Quick tour of a restored National NC-57B receiver. Had to replace all of the paper and wax capacitors, a few burnt out resistors, and lubricate pots.

    I'm confused the radio still worked without that plug you were talking about

    I recently acquired one of these in need of restoration, probably just a cap job and a new power cord.
    If it's a receiver only, why is the toggle switch next to the speaker marked "send/receive"?

      Almost all old receivers can be muted when a secondary transmitter is in use; you can either switch it to "send" mode to mute the audio, or there's also usually a way to wire the receiver mute to the transmitter through the accessory connections in back. This way you don't blow your ears (or your speakers) when you transmit.

      @@ai6yr500 You can also roast the RF amp stage in these receivers if a transmitter starts up nearby, especially if they are sharing an antenna.

    Nice, Ben...what are the controls with the Fender knobs?

      Not sure... They are connected to the added marker generator there in the back, but don't seem to do anything (that I can tell).
