RE: New reissue KT88 versus vintage Genelex/Gec KT88

Thanks for the post, Michael. Very informative. You mention being very generous with the bias with respect to the reissue KT-88. I have my quad biased at 50ma and thought that might be pushing it a bit. Won't 80-85ma be pushing this tube too hard, possibly driving it into distortion and lowering it's power? Could that also be putting too much stress on the amp? I love the sound of these tubes at 50ma, but am now curious about adjusting up their bias. But, for me, they are expensive, and I don't want to wear them out prematurely or over-work my amp. Any thoughts?
