Dude, this is crazy, it’s like we’re working on the same gear around the same time. I have a client that has a lot of REALLY nice gear. He brought me his A-910 with one channel of all shorted outputs, one of the MT-200 devices had even exploded. Got the full treatment, he wanted the best of the best for it. Man it sounds nice. Not the most fun to work on. And yeah it runs hot! Also weird you need to bias within the first 70-120 seconds of being on. Odd duck.
