It's a Carrera, running either octal or nine pin...
Ok. Maybe a bit OTT, but the amp went pop fizz bang yesterday on the 9 pin setting. It had done that before (on the octal) but only when I was experimenting with a very old kt66 that someone had lent me. I switched it off, removed the big bottle, replaced it with a very old Brimar 6v6 and fired it back up: it's been fine since.
But yesterday playing on the the 9 pin setting (which was running an almost new JJ EL84). It went bang.
Took the back off this eve and had a look at the 84; it was all frosty at the tip and when I tried to remove it, the glass sleeve just came away. It now looks like this:

Did I just get a dodgy el84 or should I be asking the local amp chap to be looking at this in more depth?
