Re: Mesa Boogie Simul Class 2 Ninety
I'm not entirely what your question is about, but the 2:90 is about the finest and highest quality power amp you can buy. The caps looks fine, as they really would only need to be recapped if it was over 15 years old and under heavy use. As for the tubes, as long as they are in matched pairs in each channel (Ruby in Channel A, EH in Channel B, etc) and they are in correct Mesa bias spec, it should be fine. The 2:90 is really designed to be maximized with the Triaxis since it can use the deep/modern/half-drive features, but will work all the same with anything else...as to why you would want to paint the knobs (those are the original ones), i'm not sure.
