Well, I got my 65 JTM45 back from Edtronics (caps and bias set) last week and I'm kind of torn. It sounds great clean and with relatively low gain (using Tele and Mullard 12AX7s, GEC KT66 into an orange cab with 73 G12H30s or a Carvin cab with blues) sounds but when I really crank on it (volumes at 2 oclock or over) it starts to sound kind of fizzy (like there's an envelope around the distortion and when the notes die out, there's still a buzz that lasts for a split second). Any ideas or is this just not one of the magic ones? I am using a Variac and a voltmeter to make sure it's being fed the right voltage... It's better with single coils, worse with the 59 burst!
