To @ psarkissian: Here’s my dilemma and I’d like your input. I know you’ll say, take it to a service center...ok, I got it. I'd just like to know if you or anyone else in this blog has experienced this issue: my DT25 started making cracking noises; it’d come and go over the period of a month or so. I could move cords/pots around and it would disappear. But last week it got really noisy, so I turned it off thinking it was bad tube. The next day I turned on the power, with all the volume pots OFF and in standby mode and I got an immediate nasty blaring sound. I checked for microphonic tubes...nothing, so I pulled power tube one (V2) and sure enough, there were white flakes dancing around inside the tube so it was blown. I replaced all the exact EH tubes but I have not powered it on. So...my question is: do you think (as I do) that it is in fact, just a blown tube, or because of that BLARING, could it be a blown modeling board? (as I’ve heard that was a problem a few years back). I have never experienced that with any other amp that had a simple tube issue. And no...the fuse did not fry...it’s perfect. Thanks
