Reads as if it's time for a fresh tape to ADC transfer with the Dolby in
line. Even using very good converters (e.g., Lavry Gold] in double
signal-jacking [D/A/D] mode is counter-indicated unless you must do that to
use some outboard analog processing. If you have the tape, you don't have
to do that. It should not have been transferred without Dolby decoding.
