Operating points are important boys and girls. I have been running the 7c5 tubes at 250v 30ma with the idea of taking it easy on the tubes. While I noticed improvements when I switched inputs, output impdance, and to ultra linear, I still wasn’t getting the sound I thought the tubes could give me. It was always a bit on the lightweight side lacking heft in the midrange. Went back and looked at the data sheet. Moved to 285v 35ma and what a difference. It filled in the lower midrange and added a touch of depth. Now we’re cooking! Currently using Tungsol 6c8g inputs. I’ll try triode again tonight and see if my triode/ultra linear hot take holds up.
