Intermittent volume drop out
Posted: 23 Oct 2013, 10:56
I plugged into my Haze 40 today for the first time in about 6 months. Still sounded pretty good. Since I bought it about 3 years ago, I've changed the speaker (Eminence GB), biased the tubes, clipped C73 and piggy backed the C73 onto C72. Also I jumpered R88. It now sounds exactly like I want it too, but...as I was playing it, just lovin' the tone I was gettin', the volume started cutting in and out. It would be loud, scratchy, soft scratchy and back and forth and then so on. If I really hit the chords HARD, it would come back for a while and then cut out again. when I've had this problem before, I opened it up, reseated the tubes in the sockets (yes they WERE loose) and everything was fine. Today I did the same thing, but still the same problem. I'm hoping maybe I only need some new power tubes; (I put in new preamp tubes) what do you guys think?
