Thanks for the tip lawdawg. I received two 200’s on Jan 9 and both wobbled. One a little, the other a lot. I was able to make shims to solve the problem but the suggestion from Scott is much neater. When I get a chance I’ll remove the shims & try the top cover screw “alignment” method.

Two questions come to mind:
1) Why there is a wobble in the first place, and
2) Why isn’t Scott’s fix posted in tips etc. section as you mentioned

Anyway they sound great. And I’m very pleased with the amps wobble or not.
