Re: Jerry's " ONLY ONE IN THE COUNTRY" Phase Linear 700 Thre
yes he is Nando, I'm havin a hard time unhooking it and finishing it. It will definately be a wolf in sheeps clothing. If people see the amp and expect the "old PL sound" they will be profoundly surprised. oe's distortion measurements on his 400 have been nothing short of amazing. 've been researching some specs on some of the higher end stuff, he's taken the PL STUFF RIGHT THERE WITH EM. aDVERTISED THD&N was .1%, my Spec .05%, all these specs were at a filter setting of 30KHZ, Joe tested his at 80KHZ, a much tougher condition and brought it down to .006%, that figure compares with state of the art mosfets and Class D switchers of today. Components and circuit design determine function, i believe the "art" of that aspect is where the figures go that extra decimal point. My hat is off to Joe.......................and a large part of my allowance for the forseeable future. I ordered 10 boards just to upgrade my Pl stuff, and Larry's 700. I'm doing recalls on Pl's I've sent accross the country, 2-400's in Maine, a700 and 400 in Cali, 2-700's here in Gillette, and of course Larry's.
I might add the distortion specs Joe is getting are besting complementary -paired class A/B amps, that isn't supposed to happen. But it is.
