Origin 20h valves replacement

Hello

I want to exchange valves in my Origin 20h, ordered some 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 IOS,

Thank you for your message, the Origin 20H has a fixed biased so no need to rebias this amp.
