I THOUGHT Dolby B reel-to-reel reference level was the same as Dolby
A...but I could be wrong...at 185nWb/m...this is "Ampex Operating Level."
A good resource for things like this is the MRL Web site.
My experience with the Advent units is that the pin/socket connectors
became noisy. The AN-180 Teac that I have seems to be performing as well as
the day I got it in 1975 or so.
