This machine was reviewed in Audio magazine in 1984. They found the computer alignment to be one of the best and most reliable in obtaining a flat response with almost any tape. The calibration includes level, bias and equalisation at 6.3 and 15 KHz. I have owned one for many years and it's still works fine and measures +/- 1.5dB from 20Hz to about 23KHz with pretty much any tape.
