This reminds me of the joke about the town that set its public clock when
the local fort fired its canon at noon. The fort, of course, fired the canon
when the clock struck 12:00.

I have an old Yamaha that is a spare machine. It has always seemed to
sound "good" however I never really ran any tones through it to see
what playback looks like. I'll have to investigate using that one as
my "standard". Back in the 70's I used to align Ampex and Scully
professional tape recorders and could A B an output pretty closely by
ear. The last few years though the high frequencies have been rolling
off, (between my ears) and so now even 10KHZ is difficult to perceive.
So I really can't rely on "what seems to sound good" to me any more. I
thought that music sounded reasonably good on the faulty channel of
the Teac until I looked at the meter while running tones. I'd still
like to find a commercial alignment tape though. I have several old
reel to reel alignment tapes made by Ampex and Nortronics I think but
nothing for cassettes. Lenny
