HI!

I have a large number of reel to reel tapes and a Tandberg TD 20A machine
that doesn't work. From the net I have found that the Tandberg machines
sounds nice, but are technically not very well built.
It seems like Revox is the brand to look out for and the types of A 77 and B
77.

What is really the difference between those two types and which one is the
one to go for?

All the best
