Overview
The DAK Mark IX was a tube-type Citizens Band transceiver sold by DAK Industries during the early years of the CB radio service. Unlike later compact transistorized mobile CB radios, the Mark IX was a rack-mount base station unit using vacuum tube circuitry and crystal-controlled channel operation.
The radio was designed for fixed-station installation and featured a wide front panel, transformer-powered chassis, and heavy-duty construction typical of early CB communications equipment.

Physical Description
The DAK Mark IX used a rack-width metal cabinet intended for tabletop or communications rack installation.
Front panel features included:
- Large analog signal meter
- Rotary crystal channel selector

Internally, the radio used transformer-powered tube circuitry with point-to-point wiring and socket-mounted vacuum tubes.
History
The DAK Mark IX was marketed during the early Citizens Band era when many CB transceivers still closely resembled amateur and commercial communications equipment.
Its rack-style cabinet and tube construction reflected the design approach used before compact mobile transistorized CB radios became dominant later in the 1960s and 1970s.
The radio was sold by DAK Industries as part of its communications equipment offerings during the early growth years of the Citizens Band service.
