the thick goo that seems to get thicker with age may impede the proper
contact. Clean out some of the goo (not all of it) and spring out the
contacts to create a firmer tension against the disc.... or order a new
control .... and plan to replace it in a few years.

This is a optical type control with a led or such with a photo
interrupter,
correct? What's the goo inside doing, blocking one of the Photo
interrupters?

Well, it was as you said. Mechanical encoder. cleaned some of the gunk off,
pulled out the contracts slightly. Put it back together.
Now, it does not want to turn up like it was. So i guess its new
control time or junk time. Well see if Andrews answers my faxes this
time.

Thanks for the help all.

Just for reference, are any of you aiwa warranty?
What kind of support do you get our of Sony for them if
you are?

Bob
