blowen fusen und poppen speaker mit spitzen sparken

[Beans]

I am selling my suped-up Dyna ST-70, and I had, HAD I say, an extra rectifier I HAD meant to throw in to the deal. So last night I opened it up for the first time and started using it. No problem... the amp sounded great. So today I flip the switch and as it's warming up I hear a loud buzz from the left speaker and as I look up, the rectifier and one of the KT88s are both arcing, and before I can sprint over to hit the switch the fuse blows.

Sure enough, at least one of the KT88s is muerte.

What the hell happened?

As a side note - IST NICHT FÜR GEWERKEN BEI DUMMKOPFEN.

Beans.......Thank goodness you still have the ol' reliable McIntosh gear. Just noticed you also have a Revox B77 Mk II. Cool.

Yeah, fact is I've moved out. I had always planned on selling this ST-120 kit amp, as much as I hate to. It sounds really, really good but I can't justify keeping all this gear, especially now that I've blown a couple of tubes.

I think I have proven the rectifier is still good. I just had a KT88 blow out. Is this the typical fashion? ...with the "blinding light show" reminiscent of the band Triumph?
