The HT-37 when introduced was one of a series of transmitters introduced (see below). Fortunately the styling is not to different from the SX-115 which I have choose to match the transmitter with. The HT-37 used 6146's in the final. The unit was designed to use the phasing generation for the SSB mode of operation.

The top view clearly shows the dual 6146 final amplifier tubes. This was a popular transmitter and is well designed.

New Transmitters:
HT-32A   1960
HT-37  1960
HT-32B   1961
HT-33B   1961
HT-40  1961
HT-41  1961
In retrospect Hallicrafters introduced 21 transmitter and receiver models for Amateur Radio from 1957 to 1961.
