EL38 in a Cronus II magnum

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I have been using EL38 (instead of EL34) in my Rogue Cronus II Magnum for a bit, but am wondering if I have adjusted the bias properly. For the EL34 I had it set to 30, but with the introduction of the EL38, I had to increase the amount on the dial to get it to even show any amount. I have it set to 20 for the EL38 but should have left it set to the previous or reduced the bias by half and then inserted the EL38, even though I the meter doesn't register anything (I hear that one should maybe even reduce the bias by 2 times of the EL34 @30, but am again not sure how to proceed). There is no red plating, distortion or the like, just a clear reproduction, actually better than the previous NOS EL34 they replaced...
