I recently noticed that my SVT-II's volume was considerably lower than it should be (as in I'd turn it up past halfway before it started to get kinda loud, and it would be pretty heavily overdriven by that point). I examined the bias today and found that I'm not getting any reading between ground and bias test point 2. Between ground and point 1 I was getting around 50 mA, and it's reading the same between test points 1 and 2 (it's supposed to read 0 +- 0.01 there, according to the instructions). I moved the tubes around to see if the problem would follow them, but to no avail. Does anybody know what could be wrong? By the way, what do the two bias test points/adjustments correspond to, anyway? Is one of them for the push side and the other for the pull side, or what?
