Ok, if you say so. My only experience with a known gassy tube was a
3-500Z in a Heathkit SB-1000. I powered up the amp after it had been
sitting for about five years. The fuse blew instantly. I connected it
to a variac and slowly raised the line voltage. The tube started
glowing a nice purple inside and was obviously gassy.
My AL-1200, on the other hand, developed it's problem relatively
overnight, so gas may not be a likely culprit. I mentioned it only
because of the possibility. More likely, something internal shorted.
