My first proper r2r was an Akai X200D
Married with a Kellar KDB1 unit.
Basically 2 indpendent mono dolby B units. And you could dolby up on one channel and dolby down on the other. Neat for bouncing in those days.
All before the 4 and 8 track stuff on 1/4" tape. Was able to "borrow" a Revox now and then as well - luxury!
