most bypass modes take the tube stage completely out of the path. you're hearing input straight to output and whatever you're doing to the bias isn't hitting the speaker at all. some bypass modes still load the input though, so it depends on the design. what amp were you working on?

I spent yesterday cooking bias tubes in a power amp for three rounds, listening for the tone arc and coaxing the signal from static until I realized I had the knob set to 'Bypass' the whole time. I really did work hard to reinvent a dead channel. feels like we punish ourselves while we look for the obvious?

just routed to ground. i was driving a voltage that didn't exist because the bypass switch was starving the plates. traced that ghost in the wiring for an afternoon. feels criminal.
