I agree Rob; a fraction of that massive HV PS capacitance would create an unperceivable difference in the Tx performance and signal at a distant Rx station :-) Leigh VK5KLT load B+ supply. What is th
Although I understand the point being made, filter capacitors, no matter how large, do not provide "regulation" any more than a big flywheel takes the place of a governor on an engine. Regulation req
I certainly did. I looked up what the commercials did. No large glitch resistor, just current sensor and fast cut off for the transformers. All have choke filter inputs, so have mine. The largest fil
For you folks that go on and on and on abt diminishing returns, why dont you toss the arrl book in the trash..and find out for yourselves. later... Jim VE7RF -- Since that is the only part of your st
All good points Carl. When I use my RF speech processor the Po and Ip come up to almost static values and represent a roughly steady load on the HV power supply. As for residual ripple, tube amps hav
Yes Peter, you won't go astray if you take your clues from what the leading not 1953. Just take a look at the henry 8k amp power supply. They use a 6000 vac sec + resonant choke + a pair of 16 uf oil
My result on a 3-phase power supply with a 3800V AC transformer is a drop to 5162V from 5400VDC at 2.4A load. The capacitor is just 2µF, no choke input in this one. That capacitor does the same as a

** The tests Ive run were replacing the 200uF in various Heath SB series amps with 330 or 470uF, with and without directly grounded grids in the 3-500 amps. Plus a few other brands going from the st
