NSM started using the ortofon needles with the Prestige2 and City2 models,
IIRC.

om...
a missing switch, I don't see anyplace where a switch would be wired
to. Does anyone have this same box that could take some pictured of
their carriage and send to me? I would really appreciate it.


Some NSM carriages use a microswitch, as described in your manual.
Some use an optical switch instead, which is probably the case with
yours. The optical switch is mounted to the carriage PCB and points
straight back towards a metal strip under the record rack. Part of the
strip is black, and part is not. When the carriage passes the point
where the strip changes, it knows that is the home position, and it
figures out the record positions and the ends of the rack from there.

Good luck troubleshooting it! Those can be really annoying to get
going, in my experience.


I do see the optical switch mounted on the pcb, but I don't recall
seeing the metal strip that is part black. I will have to look closer
when I get home. If I hit the scan switch, it moves all the way to
the left. Hitting the switch again, bumps the carriage right, then
back to left. It seems to know that it has hit the far left. I am
wondering if this is even the carriage that is supposed to be in this
machine, since it also has the "ortofon" needles which I thought were
on the later models. I think I finally have the power supply troubles
fixed and the computer comes up, so I think it is time to put it all
back together and see what happens. Those damn 20+ year old
electrolytics will get you everytime.

It does seem to be quite a pain from what I have read. The price was
right though, $20 after raiding the quarters from the coin box. And
my wife really likes it, so I guess I will have to keep fighting with
it.

Thanks,

Mark
