Good advices for a newbie (threading tools lathe)

Hi
I'm trying a different amplifier with 6sn7 single ended +el84 pentode. I built the circuit in rapid mode, on the table. Unfortunately I havn't 5k output transformer (only 2,5k), nor local shop has 20w 5k resistor (yes, here the quality of the shop is everyday worse!).

few words about circuit, tomorrow I connect the amp to the plasma and see what happen. Compared to old pcl82 amp this new sound better and louder. I think I need to check every stage but at first sight with same clean 0.2v rms imput I got 5 volts good output, it's more than 2x old amp (clean 2,5\3w). If I close an eye I can run circuit up to 9\10v output with some distortion, but still acceptable (5/6w). Leaving out the measures, connecting a speaker to outpu,t sound is really louder, and that's what I need in order to check spl connected to flame.
That maybe only an experiment, soon I'll try El34 tube, maybe in the same good octal relais socket, maybe the final tube I'll choose

Good thing, despite long cables and chaos, no hum, buzz, or strange sound!
