I got my new Budda Super Drive 30 a month ago. Gigged once. I'm noticing that this thing puts out some serious heat! The metal plug on the speaker cord is actually pretty warm to the touch after a practice of a gig. Is this normal for all Budda's or just the SD30? Will this kind of heat shorten tube life considerably? I only gig 2 x a month so I'm not too worried about tube life..more curious than anything. BY the way...what a great amp! THis thing has the best overdrive sound I've just about ever heard. Almost a "plexi" sound with the drive at about 9:00. THen, bring the drive to about 1:00 and your in Brown Sound heaven. Just thick with no hint of "buzzyness" that I had with other Marshalls or other amps. Clean is warm..yet has a nice bite to it. Love it so far.
