This causes me to wonder if you have had to try this on an HX processed 
tape. I am only aware of one pro deck with HX Pro, the studer A820, and 
most people leave it turned off anyway. But it is there on some later 
models. (possibly on the A827 as well, can't remember)

Seems like a horror story for your process, chasing a HF modulated bias 
level.
