I think that will be the first step, to see if the pots and switches can be salvaged. Then I can start saving for some powered monitors.

I had considered that but read several reviews from people who did not get good results with the Radio Shack cleaner/lube, supposedly due to the silicon used for lubricating. Worth a try though. Thanks for all the input. After I get back in town next week I'll tear it apart and see what happens.
