Homebrew High Voltage Power Supply.  Marked as "1000V."  On my testing, it
delivers 1300 volts with no load.  Solid state recitifer system.  On/off
switch.  Pilot light (that is what the 12.6 volt transformer is for)  I
estimate about 250 to 350 Ma from the size and weight of the transformer.
27 pounds.  $30.00

Homebreww Power Supply.  500 VDC no load (estimate 250 to 300 mas from size
of transformer).  Uses 5U4G rectifier. Has bias supply variable from -0.035
VDC to
-150.00 VDC.  Filament supplies at 12.6 VAC,  6.3 VAC and 30.0 VAC.  23
pounds.  $25.00 with tube.
