Ok, I got it working but only when the + probe on the volt meter touches the + of the 12v ac going to the tube, when i move the probe off it starts buzzing really loud then when i touch the probe back on it works.

Ok, i got it working but the gain is REALLY low, so what would happen if i added a second tube to the circuit? (hook the output of the first tube to the input of the second tube and the output of the second to the speaker)

It's a preamplifier valve, it's only going to have a very tiny output, plus you don't even have a real output transformer which is going to reduce it even further.
