Does anybody have any experience with the various vintage RCA mics?
What is the difference in sound between the 77A and the 77B, B1, C,
C1, D and DX and other ribbons? What do you think a fair price would
be for a fully functional 77A with a new cable and the original desk
stand?

'fair'?
something that rare would be whatever the owner wanted.

You want one to COLLECT? or one to USE?
If the latter, buy the AEA ribbon

I disagree, since the 77 has adjustable patterns and more top end detail
than the AEA has. The R84 is a good mike, but the 77DX is hard to beat.

I think the difference between the 77 models is mostly in the pattern control.
There was a ribbon assembly change too, that Mr. Sank will know far more about
than I do. If you want to use it, you probably want the DX model, not only
because it has the best pattern control, but because it is less collectable and
therefore sells for a more reasonable price.
