JJ 12AX7, actually they call it ECC83, same tube! Wow JJ tubes from Slovakia, they are really impressive in gain, clarity, and absolutely quiet! Installed in a 100 watt Fender Super Sonic Twin I recently purchased used...Brought the beast to life! Searing gain and clarity, excellent performance and a great price! Antique Electronic Supply has awesome customer service and the FREE shipping was fast, Iam in Florida and took only a few days. You wont find a better price on tubes anywhere, Thanks guys!

The tube seem to be working the way they are supposed to. I'm still not getting any sound so the capacitors are next.
