Thanks for the feedback. I was considering going lower to 12ay7 but today I spent all day playing through it and I think I’m sold on the 5751. I plugged in 2 (Per DG)and can go clean almost all the way unless I dig in of course.

I also noticed that my cheap jazz partscaster with a neck SD 59 with A2 is sublime. However my ES-330 like Peerless (hollow, P90s) does not shine.

I’m also really happy with the speaker.
