Does anyone have service info on this automatic turntable, please ? Does not
appear to be a UK model, as there is nothing for it on the UK Panasonic
service website. I am particularly interested in how to adjust the set-down
/ pick-up points. Both are slghtly late ie set-down point is a groove or two
into the music rather than on the lead-in area, and pick-up point is just
beyond the end of the run-out area. Almost as if the arm is slightly
clockwise rotated with respect to the position sensing plate for the three
optos, but I can't see any immediately obvious adjustment screw, or locking
screws. Failing there being any simple adjustment, I think that the "S"
curve of the arm is gonna become slightly more pronounced ... !!

Thanks for that. I went and took a look, and interestingly, the SL1610
appears to be completely different from the SL1610 Mk2. The straight 1610
seems to be semi-auto only. The Mk2 is fully auto. It has no size set
switch. Instead, the disc size is sensed automatically by way of three sets
of three plastic prisms that sit just below the surface of the turntable
mat, and have light from three infra red LEDs that shine through them. The
user manual for the 1610 has detailed set up instructions for the set-down
and pick-up points, which are adjusted by a pair of screws, accessible from
the top through holes, which is what I was expecting. The Mk2 has no such
corresponding adjustments ...

Anyway, the problem is now cured. As both the set-down and pick-up positions
were both wrong by the same amount, and in the same direction, I figured
that it was more likely to be a case of mechanical abuse, than one of
mis-adjustment. Careful examination of the tone arm indicated that it may
have suffered some - how shall we say - stress? at some point in its past.
So I gave it the tiniest amount of 'stress' the opposite way ...

When retried, it set down smack in the middle of the lead-in area, and
picked up similarly in the middle of the lead-out groove, so job done,
wrapped up, and ready for return to the owner ! Thanks again for your
efforts. Appreciated.

blimey, who would have thought that the mk2 bit meant we were talking
about almost a different model. mine must be the 1610 as it has the
selectors etc.

glad you fixed it and liked the rough 'n' ready cure! ;-)
