Jadis OR bias value for Mullard RL34 and KT88 help

Sure Joe, you know what I have a rarely used one that I don't need to protect so carefully, I will tell you here try stmechanic1@comcast.net I can only access it occasionally so forgive me for a slight delay. Once there I will update you on my current addy. Thanks for asking it has been a while my old friend!

Thank you all for taking the time to help me. My JOR is up and running sounding, really sweet with Chinese EL34s and Teles 12AX7 ribbed plates.

Fantastic post for JOR owners. I like to try quad psvane Tresaure Mark II. Did anyone have any reviews and sonic experience with these tubes. Link below.

Thanks for the link Sumonkabir those tubes look cool and the sales pitch seems plausible even if we can't confirm that it is meaniingful of true. The other possibility that I mentioned but haven't done is to get Gold Lion re-issue KT-77s which are a somewhat higher powered EL 34. I don't know if the bias needs to be changed but it shouldn't be majorly different than an EL-34. To be safe and certain just get a truly matched quad from a good vendor. If not buying from Trelja who on occasion sells some Chinese tubes get the from McShane Design over on Audio Asylum or by search. He really matches his tubes and trys every one of them to avoid sudden infant tube deaths.
Another tube to consider is theso called fat bottle Electro Harmonix 6CA7 which are equivalent to an EL 34 and are direct subs. They put out a really big sound although th Psvane tubes look a lot like the dimension wise. We talked earlier in the thread about the input tubes.

Hi,

Can anyone give advise on DA-8 tube biasing? What will happen if amp is not biased properly?
