Dave> Jim, not quite sure what you mean? He's wanting to know if you were ever able to click on the links and make 'em work? The original message was: ============================== Hi Guys, I have been working on two HV regulator circuits in the past year where I needed +375 volts at up to 100 ma. In the first case I had 600 volts to start with, so I used a tube circuit. In the second case, all I had was about +430 which dips to about 390 at maximum output, and reduced AC line voltage, so I went solid state. My two circuits are here: Tube version: http://pages.prodigy.net/jcandela/CentralElectronics20AModifications/CE_20A_QRO_Power_Supply.jpg Solid State version: http://pages.prodigy.net/jcandela/Sherwood_S8000/HV_REG/SS_HV_VOLTAGE_REGULATOR.jpg The first circuit shows my complete power supply in my Central Electronics 20A QRO #2 rig. I used a pair of 7591's in the RF final to make up to 12.5 watts AM output, or about 55 watts PEP SSB output. I ended up with a 6W6 in the series regulator as it had more emission than a 5V6, even though the 6W6 only had 5 1/2 volts on the filament. This regulator is always at +374, hot, cold, month after month. The ripple from it is unmeasurable (with my equipment), and dynamic load response is excellent, although I cannot remember exactly what the results were, as that was last winter.
