You need to do the interconnecting wiring, mounting, and necessary round hold drilling of the plastic case. One photo shows a finished built unit. This kit features three, independent DC power sources, to provide B+ (high voltage), A+ (filament voltage) and C- (grid voltage), for vacuum tube radios and other electronic equipment. The kit provides the following voltages and currents. BE SURE IT MEETS THE REQUIREMENTS OF YOUR RADIO. For 120 VAC input voltages only. B+ circuit consists of a standard shunt regulator, with a series string of twelve zener diodes. Twelve diodes allow more taps, and reduces component heating. Standard taps of 22, 44, 66, 88 110 and 132 volts nominal, with additional taps of 33, 55, 77, 100 and 122 available on the board. Maximum nominal current of 50mA at 132 volts. Exact voltages will vary due to component variations, and load. Current limiting is provided by a PTC resettable fuse, and conventional fuse. A+ circuit consists of a LM350 voltage regulator. Variable output from 1.2 - 10 volts DC by onboard trimmer, up to 2 amps. C- circuit provides an adjustable, zener regulated 0 - 21 volts DC by onboard potentiometer. Three onboard LED's provide indication of A, B and C voltages. Quiet, onboard 40mm fan provides cooling for longer component life. NOTE: The unit must be operated in an enclosure at all times.
