Faust Gonsett, W6VR, started Sideband Engineers in 1962 after retiring from the company that bore his name (Gonset). SBE's first product was an innovative transceiver, the SB-33, and a line of accessories soon followed. The SB-34 was announced in 1964. The new 135 watt transceiver was solid-state except for the driver and finals and covered 80-15 meters.
Perhaps the most significant upgrades were the inclusion of a built-in AC/DC power supply (selected with different power cords), and a Collins mechanical filter.
The optional Codaptor enabled CW by injecting a keyed tone at the SB-34's mic input.
Here are the specifications transcribed from Section 1.2 (SB-34 Transceiver Specifications) of the manual:
