Greetings Kevin,

Thanks for the answer, I will get myself 4 relays to be able to use a single switch for the cathode and fixed bias option. I don't really plan to mix cathode and fixed bias between the tubes (might be a cool feature but for my personal use, controlling all tubes at once is more convenient). I didn't noticed that the shape of the connection on the PCB was meant to accommodate the use of a relay but now that you mention it, it is so damn obvious ahah

Cheers!
