Looking for a TA-12, HF AM/CW tube type Transmitter made by Bendix, used in Vintage Military Aircraft. It has 4 oscillators/VFO's that can be pre-set to desired frequencie and a common 1625 PA Stage. It requires a dynamotor power supply/modulator.,but not needed. Thankyou, Al, W4TUK Irene Jenkins ispoulin at aol.com
