[Boatanchors] Dow Key preamp for sale...

[Gary Peterson]

I have a brand new Dow Key DKC-RFB, with data sheet for sale.  It was designed to soup up older, boatanchor receivers.  It requires 6.3 VAC for the 6CB6 filament and 125 to 175 VDC at 7 mA.  These are easily supplied by the attached receiver.  Input and output connectors are UHF female, also known as SO239.  If you have a late 1950s Allied Radio catalog, you will find it listed in the ham gear section.

I’m asking $20, plus ground shipping.
