Unit disassembled, lubricated, adjusted as necessary. Lamps checked, step attenuator checked (resistance wise), and the RF output checked @ 50MHZ @100,000uv with a HP 431C Power Meter. We spot check resistors for values consistant with markings as we disassemble, repair and reassemble unit. In some cases the Audio output /Mod in connector has been replaced with a female panel BNC connector . AC input modified to use a computer style connector and cord set. Cord set furnished as part of sale. Cabinet not painted, rubber feet on bottom not installed (this unit was never equipped with rubber feet). Internal audio oscillator adjusted for minimum distortion. Power supply voltages checked against manual values. Schematic available for download at BAMA.Corroded hardware replaced. This unit is ideal for those who are servicing boat anchor radios, in the ham shack, or in a teaching environment, This unit is rugged, easily repairable and very reliable. The step attenuator in combination with the analog meter provides a very easy way to determine signal level, or one could use fixed external attenuators in various combinations.
