I played tonight at home with my brand new JCM 800 2203X and my original JCM 2203 (1983) with stereo delay, etc... It was maybe too loud?! I replaced all the tube for Ruby EL34BHT and 12AX7 HG for my new 2203X... Since that all my amps have those tubes. I was wondering who is making the "Marshall" tube these days. Rock On!
