Well, as I type this I'm listening to a cassette I recorded from my 78's in
1979...25 years ago! These tapes have never been stored with any particular
care (other than being kept in their original cases). Further, these were
low-end Sony blanks...probably type I, but date from before there were other
types! Further, they are being played on a Sony "mini-boom-box"...miles from
state-of-the-art. Still, I don't hear any speed variations or similar sign
of play errors. I can't comment knowledgeably about bandwidth, since the
content is mostly acoustic 78's which demand little in the way of bandwidth.
However, Billy Murray, performing "I've Been Floating Down The Old Green
River" (playing right now) sounds very much like I recall the record
sounding...
