Please try to learn the difference between the words 'passed' and
'past'. Your illiteracy makes you seem like an idiot.

Hi Stevie,

I don't think Pusillanimous is impressed by your grammar!
What have you done to upset him? Perhaps he's just a very angry man?
Maybe we should organise a whip-round and buy him a cold beer to relax with?

" Ask Nakamichi... the engineers are helpful friendly folk.
Unfortuneately, the only way to get a response is to break into their
workplace and wave a machine gun.


Unless you talk to them nicely :-)

Hi,

I have got out my old Nakamichi 480Z cassette deck, and am testing it. It
generally works fine, and is in great condition, but there is one problem.
When I rewind a tape and then press play, it won't work. The machine seems
to attempt to start the tape moving but then just stops. If I try pressing
stop then start several times, occasionally it will go. Mostly though, I
need to open the cassette door then close it again. This causes the slack

to
be taken up and the tape to be wound on just a fraction, and then the tape
will play with no problem.


**Most likely cause is the assist belt. When you lift the lid, you
will see a large gear. The belt which drives the gear is probably worn
and requires replacement. The mechanism should be correctly aligned,
after this service, but it will probably work without the alignment.
The T/U idler may also require replacement, but this problem usually
manifests itself during play.



Any ideas? Is this something I could attend to myself?


**I have no idea if you can attend to it yourself.


At this point, replace *ALL* of the belts and thoroughly clean the reel
drive idler wheel using a rubber "restorer". If you have a torque
gauge, I think you'll find that the reel take-up torque in one or both
directions is too low.

Unless you are a complete clutz, the above procedures will not
significantly shift the alignment.

Note that this series of transport is quite different from
run-of-the-mill cassette decks. While minimally equipped, bright people
can often accomplish a reasonable alignment on a run-of-the-mill deck,
those seat-of-the-pants techniques will not work on this series. Unless
you or your expert friends or professional server can trace their
training back to Nakamichi *AND* they have the factory jigs, don't
touch the alignment. These decks are very stable and don't ususlly need
alignment unless you replace something on the head bridge or some
backyard "expert" has been messing with it. If one is careful, the
belts and pressure rollers can be replace without changing the
alignment (but I always check the alignment anyway).

Who the hell is he/she anyway?

Perhaps just wonderd through from uk.adverts.computer

Evidently, your experience with the decks has been different from mine.
Other than a minor touch-up of the azimuth, which is probably more of a
difference between alignment tapes than an actual shift of the machine
(more decks tend to need a touch-up after I change azimuth tapes), I
don't find that the decks need any mechanical alignments unless some
poorly equipped "expert" has been inside trying to second guess the
factory. (Yes, I did find an occasional machine that had a bad hair day
at the factory, but that was rare.)

I had one deck come in that had been adjusted so many times that the
adjusting screws were worn to the point that I replaced them.

Hmmm... I think the result is that it's probably a fairly easy

fix IF you
know what you are doing. Basically, I don't, so I'll have to see

what
estimates I get from repair shops. I have e-mailed B&W (who repair

older
Nakamchis) so I'll see what they say.
I would have a go at a low-end thing, as an alternative to

chucking it away,
but for a decent deck I don't think I will. If it doesn't end up

A1, there's
not much point.

Thanks everyone for your advice.

John


Just to wind up this thread, Classic Nakamichi (alias B&W) advised

me
that a full service on a 480Z runs out at £140-£220 depending on

what
needs doing.
An old 480Z just ain't worth that kind of dosh, so sadly it's now on

a
shelf waiting for me to decide what to do with it. :-(


I've got exactly the peoblem with a Naka CR3 - I was quoted 'about
£200' for a service by my local Nakamichi dealer and, to be honest, it
just wouldn't get the use to warrant it. I can't remember the last
time I even saw a cassette let alone recorded or played one :-( It's
sad becuase it was a nice bit of kit and served me well
