General Notes

Note

QST, Nov 1961, p. 199. Allied Radio catalog 1963 (copyright 1962), p. 285. The Gonset GC-105 is a complete, self-contained 2 meter station, with transmitter, receiver and built-in power supply. In a stream-lined case of contemporary design, it provides a new low profile for convenient under-dash mounting. – Silicon diodes to save current drain – Calibrated tunable receiver utilizes low-noise 6BZ8 RF tube in sensitive "Cascode" circuit. AVC is applied to avoid possibility of blocking by strong local signals. – Special gang-tuned circuits give high image rejection – Dual purpose meter automatically switches from relative signal strength to relative output – Increased modulation capabilities with high level clipping. – All tunable circuits controlled from front panel – Tune-up procedure simplified by use of broad-banded exciter stages – Fully compatible with Gonset's model 3357 VFO or 6 crystal positions available. – Output: 6 watts nominal Tube Lineup (13 total) – 12BY7 or 12BY7A: Crystal Oscillator and Tripler – 6CX8: Tripler and Doubler – 2E26: Final Power Amplifier – 6L6 or 6L6GB: High-level Modulator and Receiver Audio Output – 12AX7 or 12AX7A: Speech Amplifier and Receiver Audio Amplifier – 6BZ8: Cascode RF Amplifier – 6CG8: Mixer and Oscillator – (3) 6BH6 IF.
