Title: Hey What 504 owners,,,, 6ca7 and bias question Post by: lordsofthejungle on December 06, 2019, 02:23:51 PM Greetings~
I'd like to try out some 6ca7 power tubes on my new-to-me Hey What 504,,,, is it okay to use 6ca7 tubes in this amp without any mods? and what would the "ideal" bias setting be? thank you! |
