Three 12AX7's where older DSL's had four. They saved one by not having a cathode follower feeding the tone stack, then only four gain stages instead of 5.
Looked at the schem briefly, will try to check it out later. But it is showing a dual rail power supply. I am wondering if there is another secondary HT tap that gets switched in for the low power? Or if they are bleeding off/dissipating voltage to ground?
