hetrickaj 0 Posted September 12, 2019 Hey gear heads, I am wondering if i can use 12au7 and 12ay7 pre-amp tubes with my Bogner Alchemist Head? I guess the real question is what other tube options do i have other than 12ax7/ecc83 and 6l6/5881 Much Appreciated. Quote Share this post Link to post Share on other sites
cruisinon2 2,599 Posted September 12, 2019 This is kinda like showing up on a BMW forum to ask questions about your Chevy pickup...;) Somewhere out there is a tube amp forum that would probably get you the answer you're looking for in minutes... try The Gear Page. You'll wait forever for a useful response around here.... most of us are digital converts. 1 Quote Share this post Link to post Share on other sites
