Re: [ARSCLIST] Need help with a Revox A77 [?] in Chicago

[Paul Tyler <ptyler@xxxxxxxxxxxxx>]

Ah, there's another word of which I was ignorant.  Is the azimuth related to the alignment?  Could that be why one of the channels is way muddier than the other?

Thanks
Paul

Could be the playback head's azimuth was mis-adjusted (?).

Most are field recordings I made on a Nagra on loan from the American Folklife Center or on a Revox B77 (I'm unsure of the exact model number) owned by a then brand new public radio station in Fort Wayne.  The restof the tapes are the 26 one-hour radio shows I produced using my field recordings.  After that gig ran it's course, I was left with the tapes and no machine.  The original field recordings are in the Archives of Traditional Music at Indiana University, and what I have are earliest copies dubbed on the ATM's Ampex decks.

Somewhere along the way my preschool daughter filched a light bulb out the Revox--I don't know what you call it but it was for a light activated shutoff.  I took the Revox to 20th Century Stereo on the north side.  The elderly European-accented proprietor ended doing $300 worth of repairs and adjustments.  This was two years ago, and I'm just now getting back to dubbing my tapes.
