The RK-810 was one of Lafayette’s best selling tape recorders.
It was a quarter-track mono recorder with three speeds, seven inch reel capacity, 1.5 watt output and internal 3 x 5″ speaker. Stereo playback could be achieved with an external amplifier.
Features included horizontal or vertical operation, single rotary-style transport function control, illuminated VU meter, volume and tone controls, record safety button and all solid-state electronics.
The 810A had several improvements which included tape lifters, 600-ohm impedance microphone, an improved wide range 3 x 5″ speaker, reel hubs with rubber pads and was advertised as being ‘tape spill proof’.
