Dolby level for Ampex Dolby tapes
« on: March 08, 2007, 10:22:21 PM »
Does anybody have any information on the level that Ampex assumed for the standard Dolby level on their later pre-recorded Dolby B tapes?  Since they didn't record any Dolby tones it's not clear.  I have always guessed that they used 185nW/m as the Dolby level, but I wonder if somebody has some real (reel?) information.
