[Hallicrafters] schematic of HP-1 power supply

[Doran Ditlow WA8EOW]

Ardco Electronics sells Hallicrafters schematics.  They charge $8.50 
including postage.  These are useable copies of original manuals.  I have 
bought a couple and they are ok.  Ardco advertises in QST Ham ads in back of 
magazine.

Actually shouldn't be that hard to trace wiring and draw your own schematic 
for simple power supply.  DD
