Electro-Voice 433W (1968–1969)

The record on the "433W" is really the record of a promotion, not an Electro-Voice product. What survives are period ads for the Viking 433W, a solid-state stereo tape recorder sold with a pair of Electro-Voice 631 microphones thrown in. The ads pitched it as $126 worth of mikes free with the deck. That bundling is almost certainly why the model shows up under the Electro-Voice name in the archive.

The ad run is well documented. HiFI-Stereo (September 1968, p.41) carried it, as did High-Fidelity (October 1968, p.113), and it continued into early 1969. Per the advertising copy, the deck is a 4-track stereo, solid-state machine with three motors, three heads and three speeds. It has monitor controls, sound-on-sound, echo, and illuminated color-coded control indicators.

Beyond those advertisements, essentially nothing else is documented. There is no manual, no independent test report and no service literature. If you own a Viking 433W or one of the bundled E-V 631 mikes, corrections are welcome.
