Re: arsclist A Concern: Ampex 611 tape

["Richard L. Hess" <ArcLists@xxxxxxxxxxxxxxx>]

Thanks, John,

This whole archive is in original cardboard boxes.

I was concerned as the acetate 611 looked and smelled worse than any other 
tape its age. It played reasonably well (eeek 3.75 in/s is not wonderful 
from that era to begin with). That's why I thought I'd mention it as an 
alert to go look at it in various archives.

I managed to get it to play well and it's now after several winds more 
tightly wound--it was very loose when I got it.

Cheers,

Richard
