|Dan Harris||Re: Help! power supply prob. More info...|
Well, I discovered that my AC line is fluctuating from roughly 118vac to 121vac at the exact time that my little preamp is freaking out! I find that my conrad-johnson power amp can take it no prob., but my preamp picks up the subtle shift in supply AC, and does the thing I describe above... Funny- I can unplug the preamp and run it off its' filter caps for less than a minute, and it does fine as it doesnt see the glitch! Any suggestions on better protecting it from subtle shifts in AC?
