EB27A Complete Kit

300W EB27A HF AMP COMPONENT SET

The EB27A HF amplifier is a push-pull linear amplifier for 300 watts of PEP or CW output power across the 2 to 30 MHZ band. One of Motorola's new high-power transistors developed for single-sideband, the MRF-422, is used in this amplifier design. The EB27A operates from a 28 Vdc power supply.
