I've got one of these coming as we speak. The website says that it has a switch that automatically biases for 6L6 or EL34 tubes. It also says that the swap should be done by a tech. Are they just trying to cover their a#$es, or is there more to it than just flipping a switch, like say requiring the tubes to be in a specific range, or possibly actually biasing the amp after the switch changes the pin outs?
