Steven, thanks for the descriptions. I recommended the AEA 84 (still am as
both a results and price/practicality thing) and -was- going to post that
'why' is that I've never met 77 that I like, esp compared to a 44 or say a
639A Altec, but now you teach me that it's important that all of the 77's
I've played with were -D- versions with the shutter thingie and only the
full open bipolar setting held any sense of character for me.

The 77A/B/C are, indeed, completely
different animals than the D/DX. They are double ribbon mics, with the top
ribbon section
being bipolar/velocity & the bottom section omni/pressure. The two sections
are summed to
produce the cardioid pattern, or, in the 77-C, a switch selects between omni,
bipolar or
cardioid by selecting either or both ribbon sections.
... The
77D/DX is a single
ribbon, with a shutter plate on the back to vary backwave exposure for pattern
control. The
only difference between a D & a DX is a stronger AlnicoV magnet on the DX,
producing 2dB higher
rated output.

What do you think a fair price would
be for a fully functional 77A with a new cable and the original desk
stand?
