? peak power is related to anode supply volts. When the anode begins to
draw heavy current, the charged filter C initially delivers a bit more
volts for a mS or so..

? HV sag depends on duty cycle. SSB duty cycle is typically 15%, except
on Channel 6. . CW duty cycle is about 30%.

? Because CW vs.SSB HV sag is different with an unreg. HV supply.
