>speaker it measured .3 ohms or something like that, it didn't measure 3.2 ohms like it should of.
There is a difference between dc resistance (what you a measuring with your meter) vs ac impedance which is what tube's plate needs to see on the primary and the voice coil / 2ndry of the output transformer. Will it work yes. But there might be a bit of a miss match. Does it matter? If the audio is distorted badly you may want to try a different impedance spkr or opt.
With the problem as you describe I would suspect perhaps that the voice coil is stuck to the pole (cone won't move) or there is no hv on the plate of the output tube. A short C-8 would do it.
