The first one - simply because when the pot is NOT cranked fully open, the output tube's grids 'see' less resistance coming to it.Tonecat wrote:So which method is better sounding? Using the 250k with no bias resistors and the 2.2M on each section of the pot, or a 500k pot with 400-430k bias resistors?
Keep in mind, that any resistor to the tube's grids is forming a low pass filter together with the tube's input capacity. Therefore when the resistance is lower, then there will be more highs remaining with the pot more or less closed.
Dimed although there's no difference soundwise between both!
