## Key Features & Frequency Coverage
– Operating Modes: Supports both CW and controlled-carrier AM (screen modulation).
– Power Output: Rated for a nominal power input of 60 watts to the final amplifier.
– Band Coverage: Features single-knob band switching across six amateur bands: 80, 40, 20, 15, 10, and 6 meters (covering 3.5 MHz through 54 MHz).
– Frequency Control: Operates via front-panel crystal inputs or an external Variable Frequency Oscillator (VFO).
– Antenna Matching: Equipped with an adjustable output Pi-network matching antenna impedances ranging from 40 to 600 ohms via a coaxial output connector.
Tube Lineup (4 total)
The transmitter operates using a four-tube complement along with semiconductor rectifiers and diodes:
– 6HF8: crystal oscillator / buffer/ frequency multiplier.
– 12AX7: two-stage speech amplifier.
– 6DR7: modulator.
– 6DQ6B: RF power amplifier.
Semiconductors: Incorporates two silicon rectifiers for high-voltage DC rectification and a crystal diode in the relative RF power indication circuit.
Accessory Socket: 8-pin connector for auxiliary control functions, such as antenna relays or external VFO power.
Power Requirements: 105–125 VAC, 60 Hz, 110 Watts.
