Awesome ! I agree great info. I realize also now that its when my master is up that the current goes too high for the tube. So I will check out both the grid leak resistor and make sure I have my tube biased correctly. It was a bit hot I think especially at the high volumes. I will post what I find this weekend! Thanks again. I did notice some other set ups had an extra resistor in series and I wondered why…now I know.

Just a quick note, sorry for the dumb question but is this going to be on the screen grid or control grid? Pin 4 or pin5?
