Subject: Re: [Amps] {Collins} Understanding Screen Current in a
Tetrode
When I ran a pair of 4CX250B's on Two Meters, 144 mhz, I tuned the Amp
for identical Screen Current, within Tube Limits.

## and just how do you adjust the screen current, individually, for EACH
tube ???
## On another note, on all the old tube xcvrs, like my drake T4XC, TR-4,
heath sb-101, yaesu FTDX-401, swan, etc, etc, none of em even had metering
for screen current !
