I dailed it back to 30-32ma of current draw per tube and it tightened up the bottom... sounded better to me. I have no idea what the plate voltage is on these things.. anyone? I just use a bias probe and adjust by ear.

Thanks for the help. I will be using a compubias so I will be mainly looking at IK and wattage. I think IK is mA. IP plate voltage maybe? I guess mainly the end result is the wattage reading. Its a little different way of biasing but it seemed like the safest to me and fastest. I have yet to get to it I wanted to see what others have been doing, or been told to bias at. I will most likely take a reading of the current bias reading before changing them out, but even then they could have drifted by now.

wheelman... what were the readings on your compu bias? And what were your final readings in order to achieve the proper wattage (25watts).
