All I ever used back then (with very few exceptions) was TDK SA.
When I made bias adjustments, I could not hear any difference/effect as I went through the entire adjustment range. I think I pretty much ignored t from then on...
I think the type II would have been based on the SA (most manufacturers did), but I don't know for sure. Mine was a "demo" unit, so no box or manual.
I had a Sony CD player at the time as well (no idea what model), which I used as a transport feeding my D2A. I remember it had a "peak search" function, so you could locate and replay the highest peak of a CD track. While that looped, you could precisely set the recording level on the tape deck. I liked that feature.
