Hello to all this is audioworkshop1.com we have 2 Nakamichi 680zx decks in for service with the same problem... when we try to calibrate them in either the source or tape position we can hear the 400hz tone but not see it on the FL meter display, the units record/PB perfectly... we have totally overhauled them both and gone thru the calibration sequence from the service manual. Can we be overlooking something obvious here?
