[QUOTE="FarT_Rhin0, post: 107054, member: 3016"] I have the same exact question but funny how I've been looking through the forum and no one has answered this yet. I changed my stock Ruby 6L6GC tubes for a matching quad of JJ 6L6GC's and when I read the bias, it was at 106mv. my question is "is that the sum of both tubes current or the current going through each?" I tried lowering the voltage many times, went from 95 to 90, then 80, even tried it as low as 44mv (that's as low as my bias pot would allow me to go) but now I'm back at 64mv, assuming that 2x32mv = 64! lol there was no way I could reach the 23-35mv as stated in the manual. so what am I doing wrong here? any help would be greatly appreciated.
