The EICO Model 720 is a very "clean" 90 watt CW, 80 thru 10 meter
bandswitching amateur transmitter. This exceptionally conservative,
stable high efficiency electrical design is housed in a "low-silhoutte"
cabinet to permit its use in normal living-room space. Some important
design features are one-knob bandswitching, one-knob power, tune and
operate switch, final amplifier grid drive control without detuning
oscillator; oscillator keying for break in operation; a "novice limit"
calibration (75 watts) on the meter; matching antenna from 50 to 1000
ohms. External plate modulation terminals permit use as an AM phone
transmitter delivering up to 65 watts plate power input with the EICO
Model 730 High Level Universal Modulator-Driver.

Features
--------

1. 6146 final amplifier for full 90 watts CW input.

2. Completely sealed cabinet and careful by-passing and choking of all input and output
   leads for effective TVI suppression.

3. Protection of final amplifier is provided by a clamper tube circuit when a loss of
   excitation exists.

4. One knob bandswitching - no coils to change.

5. Final amplifier grid drive control without detuning oscillator.

6. Auxillary power socket provided.

7. One knob power, tune and operate switch.

8. Oscillator keying for break-in operation.

9. No shock hazard at key terminals.
