replacement of 20h valves

votes

 Hello I want to exchange valves in my Origin 20h, ordered some aol login from Tube Amp Doctor. After I exchange them do I have to rebias it? Is there a manual for rebiasing? I wasn't able to find anything which would give me even slight bit of a hint about it .

thanks

Hi Rio,

Thank you for you comments, the Origin is a self bias amplifier.
