Sixty years ago this month, the January 1961 issue of Electronics World carried this ad for the Hallicrafters HT-40 transmitter and SX-140 receiver for the 80-6 meter amateur bands. They were available assembled or in kit form. As a kit, the transmitter retailed for $79.95, and the receiver, $94.95. Assembled, the prices were $99.95 for the transmitter and $109.95 for the receiver.
The five-tube receiver was billed as the lowest-priced amateur band receiver available. The transmitter had a DC input power of 75 watts to a 6DQ5 power amplifier, with a 6CX8 serving as crystal oscillator and driver. For AM, it used a 12AX7 audio amplifier and 6DE7 modulator. Both units featured silicon high voltage rectifiers.
I’ve never seen the receiver in operation, but the HT-40 was my first transmitter as a novice, and I used it to burn up the ether on 40 meters in 1974. I used that transmitter for my first few months as a novice before upgrading to a Viking Ranger with VFO. When the transmitter first came out, novices were limited to crystal control, and it made an ideal novice rig. When the licensee upgraded to general (or even technician, thanks to the presence of 6 meters), the new licensee could get right to work on AM.
