Hi Jim,
You may view the Eimac numbers for a 4-1000A in GG on my website:

Two tubes will be very close to 50 ohms input impedance. They will
also lower the output impedance easing the Pi-Net requirements.
A lot depends on how much Plate V you're running.

I have two Linears that use 4-1000A tubes. One is a single 4-1000A
and the other has two tubes in parallel.
Is there an advantage of one over the other if both are run at the
limit for the Ham Bands? Even the single tube will not be over
stressed at that level with 3500Volts on the plate. Will the drive
requirement be lower using two tubes?
I don't understand why the two different designs were built as they
were both built by the same Ham. One must have had an advantage.
