Not to reply to my own message, but I was able to adjust it with an
allen key, through a small slot... not too fun, and to top it off, the
grado is lighter than the table is designed for (i.e. weight pushed
all the way to the pivot), and tracking really light (I made a
makeshift balance, using a dime as a reference weight... the tonearm
flies up... ) I'd guess it to be tracking around or slightly under a
gram. I'm going to drill out some of the counterweight when I have
more time.


You could attatch some weight to the headshell. Maybe a dime or two to
bring it into range?


I thought of that too... it might be a lot easier, actually. A dime would be
more than enough to bring it into range, all it really needs is half a gram
to a gram. This will be much easier to play with once I get a scale of some
sort. I had this idea that adding mass would be a bad thing, performance
wise, but I guess if it's only a gram, why not.

I have another idea too... has anyone tried this? In the bad part of
downtown, all of the pawn shops have signs in the window advertising
"mini scales $10".


These same scales used to be sold for setting tonearms. They just had a
little hook instead of the baggie clip. You can improvise a way to
attatch it to the headshell with a paper clip. Of course you'll shift the
zero point of the scale.


Thanks for the confirmation.

Now, continuing on the topic of turntables, this unit has a servo motor with
4 wires coming out of it. Now, I know it's a fairly cheap turntable, but
after using it for a while I realized the wow is noticible. Much like an old
16mm movie projector, but to a lesser extent. I took it apart, oiled the
bearings in the motor, and the centre bearing (with 3 in 1).. I also cleaned
the pully, and the surface of the platter where the belt sits. and still...
it persists. Would a new belt help, or is this a designed in problem? My belt
does look to be in decent shape. I really like the concept of a drawer
loading table, and I'd rather make some modifications than give up on this
unit just yet. Pioneer seem to have spared no expense on making the unit
weigh 20 lbs, and stuffing the box with electronics, so the wow is troubling
me.
