Question for those with a signal generator please. Looking at various calibration tests in boombox service manuals,they indicate for example inputting -20dB line in @ 1kHz to check the vu meters. I understand all about the two different scales of reference and how you convert to millivolts...but which one do boombox manuals from '78 to '85 actually use? dBu I'm guessing...
Thanks to anyone who knows!
