How can I tell? I heard if the bias is cathode based I can just plug in new tubes and play, but for a manual bias I have to do it myself. Thanks
i would think it would say in the manual, but i dont know if all amp makers woudl tell you straight out.
My amp, b-52 At-112 says nothing about biasing in the manual.
well seeing as how im finding videos on how to bias it when i google 'b-52 at bias', im going to say its not cathode bias.
What if i when I'm changing the tubes, I put the same kind in. Do I still have to bias it?
