Speaker is broken in two places... It's a goner I think. Note the lovely holes in the mesh that link up perfectly with my ruined speaker. I can get some silicone today (mine had dried out) and have a go at fixing but I'm doubting it.
On another note, I ran my T-max at 8 ohms and it now has serious problems. It cuts intermittently, which I can fix only by cursing and tugging on my Graphic EQ for two to fifteen minutes. It's almost certainly not because I ran it at 8 ohms, but because my repair guy is an anus. I don't want to use him again but if he didn't fix it right the first time he owes me a fixed amp.
