My big Johnson
After almost 25 years of service, my Johnson 500 transmitter is down for maintenance ,repairs, and a good cleaning. It's a two piece transmitter. The rf deck is about the size of a Valiant and weighs 58 lbs. The modulator/Power Supply weighs 125 lbs. The transmitter runs a 4-400 in the final, modulated by a pair of 811's It puts about 360 watts of carrier.
