[Vintage-Audio] Re Revox Mystery

[Duane Fischer, W8DBF]

I have come to the conclusion that this Revox B77 is not a four track stereo
deck as I was told when I purchased it. Rather, it is a two track stereo deck.
Which is ok, it does have better noise suppression for near studio performance.
I doubt it is of much benefit for a typical consumer though. 	
	
Question: Is there any way to know for sure that this is a two track machine, as
in markings etc? How did Revox designate a two track and a four track deck?		
	
I based my conclusion on a tape I recorded on both sides in stereo on a
different deck. When played on the Revox I could hear one track playing right
and another playing backwards. I am told this indicates it is a two track
machine. Based on all of what has happened, it certainly makes sense that it is
one.
