The top of the Knight range
for 1963, the 4310A recorded and played both in half and quarter-track
stereo. Two 8 watt push-pull “Hi-Fi” amplifiers drove
two 6″ speakers. Three speeds were provided plus an automatic
shut-off. A three digit counter and two ceramic microphones were
also part of the deal.
Six pushbuttons controlled the tape transport functions: Stop, Record,
Rewind, Wind, Play and Pause
This machine was featured as “our finest stereo tape recorder”
in the 1963 Allied Electronics catalogue.
