Information
The new EICO Model 730 is a superb, truly versatile
modulator at low cost. It can deliver 50 watts of
undistorted audio signal for phone operation — more than
sufficient tomodulate 100%the EICO Model 72090-wattCW
Transmitter or any transmitter whose RF amplifier has a
plate input power of up to 100 watts. The multi-match output
transformer matches most loads between 500 to 10,000 ohms
and the unique over-modulation indicator permits easy,
reliable monitoring, thus precluding any need for a plate
meter. The Model 730 provides low level speech clipping and
filtering with peak speech frequency
range circuitry. Low distortion is also achieved through the
use of feedback and the employment of premium quality audio
power pentodes. The vacuum tube rectifier is the
extra-rugged, slow warm-up GZ34, which eliminates high
starting voltages and lengthens electrolytic and tube life.
Balance and bias adjustment controls are also provided and
the finest quality, conservatively rated parts are used
throughout. The Model 730 is also an excellent low impedance
driver for a class B high— power modulator.
