My Deluxe Reverb developed a nasty issue last week. 10 sec YouTube link attached. I reseated all the tubes, did the tap test on them and they sounded fine, however now it the chassis/cabinet seems to get extremely hot even after a short time of being on. To the point I can't really keep my hand on top of the amp without it burning a little. The amp was re-tube about 1 1/2 yr ago, it's a Alessandro handwired DRRI. I'm not sure of the life span of those tubes but I don't play hours on end or gig but I might take it out once a week for a practice..... Any ideas?
