Ok, when it comes to amps, i'm clueless. Here's my problem. It has a tube pre-amp, and had not been coming on everytime i flipped the switch. Like "FLIP ...Cunk..fade....." then i would do it a few more time, and nothing would happen, or it would finnily come on. and like a idiot, i ignored it. after travaling home in the VERY cold weather, with my amp in the back, i plug it in, it has the same problem, just now, when it DOES come on, i get no sound, unless i crank the gain and master to 10. but then it's a VERY low distorted signal. HELP ME........ Please? PS: something i forgot, a very bright Flicker of light could be seen when it clicked on, you know, during the "FLIP" Phase.
