A few days ago I posted this:
>Greetings all,

this happened, but all of a sudden it's playing tapes at ~ 3/4 speed.  The LED
power indicator reads OK and exhibits this behavior while on batteries or
plugged in to the AC adaptor.

(i.e. BIG money to fix).  I can buy the tech manual for $30-40 but I was
wondering if someone out in net-land has any experience with this particular
model and/or is willing to send me a copy of the point-to-point schematic
diagram for this little guy.

a diagram, I'm a little lost dealing with all those tiny, surface-mount
components.  Also, do these things you striaght DC motors or some sort of
servo motor?  I am studyiny electrical engineering so feel free to be as
technical as you wish.

What I forgot to say was that I had *already* looked inside of it and already
tried to adjust the speed potentiometer...it couldn't quite get it up to
speed...
any suggestions?
