Hello from cologne, I want to try a another tubes in my new Monza head. Pre-amp tubes is no problem. But what is going on with changing the EL84`s and the rectifier tube? Is there a bias setting needed? The original JJ and Sovtek tubes are working great, but I want to try two NOS Tungsram EL84 from `58. Perhaps a change of the rectifier tube. Hoping for an answer....

No need to re-bias. As far as I know, all Dr Z designs that use EL84s or equivalents do not need bias adjustments for tube changes. You should be fine with your tube experiments. Have fun!
