There was an article a few years back in Audio Amateur that featured an op-amp and a small valuie resistor in the output tube cathode. It formed a bias servo that worked well in the audiophile amps I used it in. I just don't think bias is that critical anymore. Once set (and with separate pots per tube), and if checked periodically, it shouldn't go too far unless your tubes fail or are of poor quality.
