I'm here guys. Sorry to hear Josh that 1 is a rattler. I just changed out a Penta 12AX7 that had a rattle. It was in the Marshall. Its a Chinese version of a 9th generation Shuguang. It happens. Maybe there's a reason for it like Marty's saying or it just went bad.
Looks like me and Marty are going to be experimenting with the " Lunch Box" a little. Sexy it up with some nice NOS power tubes. Gonna be fun to hear what happens. I'll be mess'n around with some more 12AX7's in the mean time and see what kind of tone changes I hear and feel. I've got some NOS thanx to Marty and some current stock too. They will work in the Marshall and NT. Lots of fun!
I agree the NT hides nothing when you play it. It shows ya whats go'n on and what ain't happening. Its raw and cutting and sits well in the mix with my fellow blues-er. I like it so far and we still got room to tweek.
I think I may get Vox's matching cab when it comes out if I have money he he. It will have a GB in it and I think that would go well with it. The K100 actually sounds good with it as well. I'm glad I had something on hand that was decent to demo these tube changes and hear the NT with.
