RE: My take

Hi, my experience with the VTA70 driver, the same as used in Charles' amp, was that it's the least traditional tube sounding of any of the driver boards that I've had in the same amp or any of my other amps with even changing it to have carbon comp resistors and paper in oil capacitors. It's more of a modern/sterile tone. With the right speakers etc I could see it really hitting the spot.

Charles, you can try to up the bias a bit to 45ma etc and see if it fills out the sound before you buy more output tubes. The VTA70 biasing is on the conservative side and gives one some room to experiment.
