Repair of a Cyrus MonoX200, exploring its internals and some of its mechanical quirks

A pair of Mono X200's. One had a fault on the input selector and both were for service. Service routine is the same as the MonoX seen in another video. We look at the differences in the X200 compared to the previous generation. We then look at an embarrassing resonance issue present in all these X200/X300/Signatures and take some steps to sort it out!
