Description
The RK-675 was a hybrid unit using transistors in the preamp section and valves in the
amplifiers. The deck was driven by a heavy-duty 4-pole capacitor-start motor.
This was a quarter-track stereo recorder featuring auto shut-off, sound on sound,
two 6″ x 4″ speakers with “side-flap” reflectors,
push-button transport controls and came supplied with two dynamic microphones. Price when new was $159.95.
Lafayette also marketed the same machine in a fancy teak veneered cabinet
and majestically dubbed it “The Criterion 1000B” with a $US189.95 price tag.
Eager to cover all bases, a
tape-deck-only version as the RK-650 for $109.00.
