Thanks Gilly; Your knowledge is impressive.

I see the dot you're talking about but I don't see any H or V markings. Both sides are oriented the same so I thought I would just move them to the other end of the scale and mount the changer the other way and see what happens. My question is: can I just poke the dot with an awl and move it to the other end or should I unscrew the cover and do it that way?

When I resolve the skipping issue I'm going to take your advice and buy the appropriate adapter and cover. I've seen the cover on eBay for relatively short money. Thanks again.
