The EL34 for me!
I put a quad of these EL34B's into my Rivera KR100 (Knucklehead Reverb) as a replacement for the Valve Arts I had in there previously. When I originally purchased this amp it was stock with the Winged C's which were amazing. Sadly pricing is out of my range for them now and the Valve Arts I got from Rivera were not very favorable. I was turned onto Tung-Sols by my good friend and am extremely happy with them. Great bottom end and the mids are fantastic. Definitely THE tube for me now.
