Hello , i just got my hands on a Dallas 50 1x12 combo. I am trying to figure out the order of the preamps , meaning where to put the 12AX7 vs 12AT7 . The location of where to put the preamps is not inside of the amp. Also the amp came with 3 12AXs and 1 12AT7 . Any help would be greatly appreciated and if you have any tips i would love to hear them . Thank you guys !
I just acquired a PRS Dallas 50 : help please

As far as I can tell, it came standard with two 12AX7 and two 12AT7 preamp tubes. Looking at the back, it looks like this:
6L6GC 6L6GC 12AT7 12AX7 12AT7 12AX7
Power--Power—-V4——V3—-V2——V1
According to what I’ve seen, this is right but you might want to verify that with PRS, or someone who currently has one! It’s possible someone swapped in a 12AX7 when they didn’t have an AT. It would work, though it’s a bit hotter tube.
Here’s a link to your manual:
