SAE C101 cassette

Audio Proz Inv #: 40516

Three head tape deck. with front panel bias and record levels, digital counter, LED metering. Calibration speed/alignment of heads is excellent. Excellent wow and flutter spec. ( I specialize in restoring items like this (much more in storage) and these are perfectly calibrated with new belts installed. The condition is literally “as new”. The proper adjustments have been made to the spring tension in the idler drive, head retract mechanism (they all need this work at this age point). Be aware, these machines will often fail to lock in play if you try to cycle from FF to Play in one step. Although it is SAE, these were manufactured by Inkel Corp in Japan, which is where a lot of later SAE stuff came from too. They have excellent audio performance; similar to a Teac 122 or Nakamichi.)
