90810 operations manual
The 90810 transmitter worked on 20 and 10 meters but could also be used on 6 and 2. Power output from its 829B final was 75 watts. Behind the panel, the transmitter's component parts were a Bliley CC0-2A crystal oscillator and Millen's 90811 amplifier. It used plug-in coils.
Higher output up to 144 watts is possible with forced air cooling. Band switching is accomplished with Millen 48000 series coils.
