Regulating screen grid voltage?

Stan | Regulating screen grid voltage? Hello, Is there a trick to regulating the screen grid voltage on a 6L6? I had it ~ 1V under the plate V but then it drifted up about 1-2 V above the Plate.Is it crucial to have it under the plate V? Could this be causing my Dumbell clone to distort too early? All other DC votages are ok. Initially, I just put the pre-amp section in and it sounded great! But after converting to the Dumble power section, it sounds like shit. It seems as though I can hear my clean guitar in the distortion with to much high end. Tried the bassman trick with a cap across the PI plates which cut the highs a bit but distortion channel is definitely not as sweet as before. I still have the 20 watt OT but it was way louder before distorting with the previous output section than the one I have in now. I still have yet to put it on a scope to see just where the signal is distorting. If anyone knows of any remedy for my dilemma , I sho wood apeeceeate it. Stan |
