Hey all, I'd like to be able to check the bias myself and as much as I'd like to think that I'm pretty good with electronics, I don't feel right poking around an amp with dmm probes. I was looking into getting the Bias Rite ... any opinions, info or reviews? Any other (better) tools? Both of my amps are fixed bias, push-pull, class A/B dual output tube based, with KT66 and EL34 respectively. Thanks!
