Just to update my journey. Bought a lightly used Modwright LS100. Hooked it up and got a lot tube rush out of the left channel. Turned the volume up, and the woofer moved in and out violently. Switched tubes right to left and got a very loud hiss out of the left channel (but not the woofer issue). Tried to power it down, and when I hit the power button the balance control came on. Couldn't shut it down without unplugging it.
I'm finished with tubes. I'm cursed :(
