[Boatanchors] Drake question

[Garey Barrell]

Ray -

The supply is the DC-4.  It's a solid-state multivibrator type with an 
auxiliary 120 VAC output (330 Hz) to run an R-4(any) receiver as well.

Typically sell for $50 - 75, but not very common.   The DC-3 will work 
also, but doesn't have the 120 VAC output.  (I don't think, not certain).

The Heath might work, need 650 VDC at 400 mA, 250 VDC at 200 mA, and -45 
to  -65 VDC adjustable bias supply.
