[Amps] Screen regulation

[peter chadwick]

Vic,

Seriously, I'd be surprised if anybody actually would know except by experience!

As the old saying goes (admittedly capable of mis-interpretation in the USA!) 'Suck it and  see!'

    For reasons that I won't go into, I want to put a 22 ohm resistor between a
    regulated  supply  and  the screen of a 4CX1000A. This would upset the
    regulation to the tune of 0.77 volts when the screen current swings between
    0 and 35 mA. Without the resistor, the regulator holds the screen voltage
    constant within 0.1 volt from 0 to 35 mA.
    From the standpoint of linearity/IMD would this be a problem?
