Hi Guys
Ideally, you use the plate curve of the tube you wish to use and go from there to decide on OT primary impedance.
Yes, you can use a reverb driver transformer and have a low-watt PA. It may be limited to 100mW or so, which is enough to make some sound through an efficient speaker.
The 125-series OTs come with a sheet giving 90 matches of load to reflected primary impedance. Start high and see what works.
Have fun
