I am replacing the tubes in my Classic 30, and I do not know if I need to bias the amp. I have heard that the C30 is fixed, and I do not need to bias it. But I have also heard that it is adjustable, and I should bring it to a tech. Which is true!!!!?????
You already have a thread about changing your tubes. Stick with that one - post this question in that thread and delete this one.
No, they are cathode biased
Im fairley sure its fixed bias.
