I'm looking for some input on tube selection for a soon to be delivered HC 30. This is a Ceriatone amp w/ a quad of EL 84s, 3 - 12ax7s, an ef 86 and a GZ 34. I'll be using it w/ a pair of Cel Blues and will be playing mostly Alt country w/ it. Just wondering what people use w/ these amps. new production and possibly a NOS tube for the ef 86. Any input would be greatly appreciated. THANKS!!!!
