Hi TJ,
thanks for your post and welcome to A-Circle. I have the M3 Triodes as well with the PL.
We have a thread going already, and it discusses all your concerns.
Please consider rerouting your post to the thread already going, since
we actually need more users like yourself to keep it going and make it fun.
Too many threads discussing the same/simliar topics usually go the way of the dinosaur.
No offense, would love to hear about your travails of the Triodes and tubes, others
of us are in the same boat!
