On the FedEx truck to be delivered today is my new Weber Bias Rite. I've read the instructions and checked out the Weber Bias calculator, so I feel like I'm going to be fine adjusting the bias. Here is my question. If the amp is operating correctly I'm expecting no problems biasing the amp. I'm going to start with setting the bias to about 38 mA and then checking the plate voltage, which should be between 430-450V. Hypothetically speaking, what might I see if the amp isn't operating correctly? I know I'm putting the cart before the horse here since I should probably try biasing the amp first, then report back if I see anything goofy. But I'm trying to prepare myself just in case.
