OK. This is one those ‘never hurts to ask’. I found a used MS600 at one of those estate handling houses for $125.
Figured, what the heck, I can use it instead of the MS200.
Rack ears were installed, which I do not need, but the two small silver panels that slip in after you remove the ears were missing. Anyone have pair sitting around that you are not using?
