1 driving 3

[Kwijibo]

How does that work? Solid state has the pills paired up. I have a tube amp, 1 driver, 3 driven.

same as transitors just has tubes.

on the 1x3's and 1x4's i have seen the final tubes all run in parallel not like a solidstate amp combined in pairs.

You nailed it, vacuum tubes are connected (fed) in parallel while transistors are connected in "Push-Pull" configuration; neither transistor being fed (conducting) 100% of the time because of the impedence matching (toroid) transformers.

Why no solid state 1X3's?

Paws, aren't some tube amps push pull?

Please dumb down the answer if possible. Not easy stuff for the GED Class of 1999 lol

It is possible (but not popular) to have an amplifier with 3 finals (or any combination of; 1X3, 2X6 or something driving 12).

Instead of using a torroid splitter/combiner (which divides/add one signal) they use a "port" which is constructed to feed/combine 3 or more signals.

Typically, you see tubes in the push-pull configuration in audio circuits where they are being fed via a modulation transformer.
