For W0GHZ (or any one else for that matter!!)

The connections for the ATT 333A amplifier are as follows:

    Pin 7   Minus 15 V    with Pin 6 as ground     Low current

    Pin 9   Plus 5 V   with Pin 8 as ground     Low current

    Pins 12, 13,  and 14   Plus 10 V at 5 Amps   with pins 11, 23, and 24 as 
ground

With a DEM Transverter at 10 milliwatts drive, I got between 5 and 8 watts 
out at 3456 MHz.

Probably could have boosted the B Plus but haven't tried it.
