I connected mine up to +/-12 volts today, without midification, though I do
have an adjustable plate currrent on my module. I was using line level
signals. It worked without issue.
One fellow who was using hotter signals was finding some distortion that
differed from when running on +/-15 volts.
Try reducing the filament current limiting resistors from 1k5 to 1k2, and
putting a 20k pot in series with the 8k2 plate resistor.
