Just read the header 7.5 ips is the top speed on a typical domestic deck of the day. Could be worse.
I recently purchased this set on Ebay still sealed. It just seemed like a pretty cool collector’s item. I don’t know if I dare open it. Would the sound on these be any better than LP or CD? I’d really like to have these transfered to find out.
Depends on the tape speed and how well the duplication process worked (high speed transfers, I imagine, perhaps not so good). If middle tape speed, I would guess part way between cassette and LP. The tracks on these tapes are fairly narrow which does not help either. Ageing might cause further losses and print through (creating faint echoes due to tape being pressed against itself in storage). Also, it would pay to get advice from someone who knows about this stuff at an advanced level as old tapes have been known to strip themselves on a single play (see “baking” suggestion in an earlier post - something I would not try by guesswork).
Hmm, it just occurred to me that if these are really 4-track, that could be interesting. My Teac could probably grab all four tracks, which might make for an interesting resource for someone wanting to make their own surround mix. Unless by 4-track they just mean stereo in each direction.
It will be stereo in opposite directions.
