Thanks, Matthew. It will be fixed bias. I guess I'm being a little too paranoid about current requirements. I just looked up the OPT for a Deluxe Reverb and it weighs something like 1.5 lbs. The Hammond 1615 weighs 3.5 lbs. This is still a pound more than David Allen's over rated OPT he sells for the DR. I have a feeling the Hammond PT might have less sag than the stock DR tranny.
