                                    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.
