I am seriously not looking forward to shipping them in for repair.....well if I am then maybe a Twenty upgrade??
I am waiting for a reply from Ayre via the dealer, which should happen early next week.
I saw on another forum that some of the earlier models had some substandard transistors that led to overheating and had to be replaced?? not sure. |
I owned MXR's for a ~5 years. GREAT amps. And yes I had your problem. It's a bad batch of power output transistors. They can be replaced back to Ayre and back pretty quickly. My dealer had MXR-20's which I wanted to love. I liked em...all the typical things, better bass, more resolute, more quiet, better attack, more dynamic...but had this elusive thing missing that kept me wanting the MXR's back in.
I ended up getting a Nagra Classic Amp ... vs the MXR20 update.
