I'm local to Mesa, and I've had a few of these. Had one that needed to be recapped. If they are played a lot - and this one was gigged regularly by a jazz musician for most of its life - my understanding is the caps can be good, just like with some old Fender and Marshall amps. In particular, I've had quite a few more Fender amps that are 20 years older that this,with original caps that work fine mainly because they have been played so regularly for 50 years. Others need the cap job badly. In my experience, changing caps does affect the tone. The stated values are clear, but the actual values on the caps just won't exactly match what the amp had, given the tolerances of the old caps.
This one was to be my keeper, and I wanted Mike at Mesa to do whatever needed to be done to make sure it was good to go. It would come with the original cord and the one replaced cap.
Anyway, it might be sold locally (waiting on that), or I might keep it. Shipping to Australia without a case would necessitate removing the chassis and shipping separately. I appreciate the interest, but I agree, this amp going to Australia at its age and value and weight might not be a good idea. I wouldn't want it crisscrossing oceans too much.
