Hey Chamai (sorry thought the post was Dante doh
and last I looked he's not a lefty LOL)
I chucked some new input tubes in my '72 a while ago (Boogie STRs, had spare after the Mullards for my MP2). It was my main amp for years. Total let down after ADA MP1/2 (and had a hum
). Back in the day I had a tubescreamer thingy with a 12AX7 tube in it, I wasn't that impressed, the amp had lots of gain but no master vol so I used a power soak so I could crank it (and still be in the same room LOL). So the screamer just made it more distorted and I wanted a volume boost for solos not so much more distortion.
Unless you really want a Marshall, I'd stick with the ADA. You could have it modded but I'm not convinced it would ever sound as good as an ADA rig (but I'm a total MP1 now MP2 convert
). I used to love the Marshall but haven't used it in many years as my MP1 (back then) gave me 128 of them at different volumes so I never looked back. MJMP modded a couple of his Marshalls so one of the input jacks is straight to the power amp stage, so he just likes the tube poweramp output to go with his preamps.
