Remember: dealing with super noob here.
Well, the preamp tube I'm suspicious of is a Groove Tube GT12AX7M (ECC83/7025)...basically a newer version of the 12AX7A (as I'm sure you're aware of). I'm suspicious of it because when I fire the amp up, all the tubes glow a nice soft orange at both the base (by the pins) and at the bottom (near the tip) except for this one. It glows soft orange just at the pins, the rest is dark.
Another question...the amp calls for a 2 1/2 amp 125 volt fuse. Will a 2 1/2 amp 250 volt fuse work just as well or must it be 125 volt?
