Bill - At a line voltage of 120 VAC, you should see about 740V no load. With idle current ~70 mA, should read about 715 - 720, and at full load (~350 mA) should be 650 - 660V.
The diodes are in a voltage doubler configuration. 73, Garey - K4OAH Atlanta ----- Original Message ----- From: "Gailey, Bill" <[EMAIL PROTECTED]> > > In my efforts to update a TR-4 and early AC-4 supply, I've been working in > low voltage areas so far (60 and 250).
