The method you are trying to use to set your bias will not produce
consistent results!

Dolby encoders are calibrated at a level of -20
dbm. The frequency response of the tapes is referenced to this
recording level also. Higher levels can cause frequency response 
variations due to tape saturation or mistracking of the Dolby circuit.
