Hi Jim, There are two aspects to consider here; the static and dynamic voltage regulation, and the amount of ripple on the B+ plate supply. In CW and SSB amplifier service the keyed and syllabic fluc

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

More immune than what? Whilst the input current will be fairly independent of voltage, the input power, and hence output power will change if the HT supply varies. That leads to a loss of linearity.

Here we can use the three phases for any purpose we intend to. Maximum power is 55KVA with my installation. In my HV power supply the 2µF capacitor is plenty, without it ripple voltage is 4%. 73 Pete

Yes indeed Dave; linearity will be lost if the B+ plate supply varies due to excess ripple superimposed on the DC. The degree of that loss depends on whether the tube is operating in Class C, AB2, AB

As can we...IF it's available and it's pretty rare in residential areas. The nearest 3 phase line is about a mile away. Our entire feed is only 48 KVA and I seriously doubt it'd handle that continuou
