What is the voltage To bias a marantz 8b?

I ordered one from amazon, thank you for the help

Thank you, I see that it is 50mA... i don’t know how to convert that to voltage. Can you help?

Thank you for your efforts, I’m not familiar with the procedure you speak of. it’s over my head, I don’t understand it. I can Only adjust the bias if I know the voltage. I’m really not a tech guy, just want to listen to my tube amp.
I have a Dynaco ST 70 that tells me to set bias at 1.56 volts.I once owned a Cary tube amp and it gave me the bias in volts.
i have a HK tube amp and set the bias at 1.4 volts for each output tube. Maybe this doesn’t apply to a 8B? I don’t know what to do

Thank you, that’s pretty much what I’ve been doing. I using some old tele’s and just wanted to make sure I don’t have too
much juice on them
