Jeff,
I have parked the idea of the triode and have ordered the tetrode boards from Dom, f1frv who has been very helpful. I am also finalising an order with Alex Ur4LL, for some gu43b tubes, capacitors etc. My plan is to run two in parallel.
I'm thinking that if I run the tubes at just below 3k ( rating is 3.2kv I think) I will have less likelihood of arcing in the tube. I also don't need every last watt out of them? Is this logic sound?
