You could flip the tubes from the one channel to the other to see if the other side drops out but I think I would just stop where you are first before something else goes.
Guessing you've checked all cable connections and etc. See if you can find a tech locally or at least someone with a tube tester.
Plenty of Line 1 users on here so hopefully someone can give you more direction, but I'd stop where you are because likely it's an easy fix. Could try getting ahold of Chris Johnson at Parts Connexion as well.
