Compare the HD-1416 to its predecessor the HD-16 and you will be astonished to find that the last year it was sold, the HD-1416—a simple three transistor CPO in a tiny plastic box—cost about three times what the HD-16 did. That’s economics for you.
The HD-1416 features a built-in speaker, volume control, tone control (on the back), headphone jack, and binding posts for the key. It also could be used as a sidetone oscillator for transmitters using grid-block keying (400 volts negative maximum), though it is doubtful that many were ever used in this way.
Originally supplied with a simple key on a black plastic base. Seldom found with the oscillator today.
The HD-1416 operates from a single 9-volt battery. The only differences in the versions are a new style knob and the color. The original is green, the “A" version is brown, and the “H" version is black.
