Guitar tube amps also use this method. But, hardly any audio amps do it. If you run a separate trans for the bias voltage it will help protect the tubes because the bias will be on as soon as the amp is turned on. Tapping the B+ will have a lag period which leaves the tubes unbiased until the B+ starts to develop. cheers, Dak
