1.1 GENERAL DESCRIPTION The ALPHA 3?4 is a high power linear Amplifier incorporating major advances in engineering and construction. It is rated for continuous service at maximum legal amateur power (FCC r u l e s ) in SSB, CW, FSK, and SSTV inodes. Exceptional power capability is achieved in combination with uniquely compact size and modest weight, through employment of a variety of advanced components including state-of-the-art Eimac ceramic/metal tubes, a power transformer with core of tape-wound, grain-oriented silicon steel (Hipersil®), and ETO's exclusive ducted-air full cabinet cooling system. The ALPHA 374 is capable of delivering normal power output, into a reasonably well-matched load, across all amateur bands for 80 through 10 meters without manual tuning adjustments. In addition, available manual controls also permit operation on out-of-band MARS and Other special frequencies from 3*5 "to 30 MHz.
