Here's an idle question with regard to the HP 7907 tape drive. The service manual says to adjust read preamp output (using a calibration tape) to 6.4V P-P.
Generally, this is working quite well, but there is an occasional tape where I believe the signal levels have "faded" a bit, leading to the occasional, but not infrequent parity error. My question for those knowledgeable with this drive is what's the downside of adjusting the gain to create an output of, say, 7V P-P? --Chuck
