I was jamming on my new Mk III earlier and then the signal started cutting out and/or becoming scratchy. I go in the Back and check for a bad tube, they all look fine, except one of the 6L6's in the outer position was a lot hotter in temperature then the other ones (the Mesa Engineering logo on the tube has dissapeared by some black/chrome looking color, but I've seen those before... its normal right?) Anyway... I turned off the amp for about 5 minutes to examine it... turned it back on for about 2 minutes... closed it again and checked the temperature... said tube was still way hotter then the others. Sound like a defective tube? I hope it is...
