Palomar 300A plug-in RELAY board for transmit only — photo 1

Description

Most of the 300A amplifier built this way have a white face plate. This is a tested, working circuit board. It worked just fine in my Palomar 300A. If your amplifier has acquired other faults in the last 45 years, CONSIDER THIS ROUTINE AND PREDICTABLE!
