Hi Kev, thanx for replying. What i am trying to find out is will my Dynaco A420 OPT be ok for use with your Dynaco ST70 transformer coupled mods. In other words, should i use the A420 with fixed or cathode bias? If its better with cathode bias, will your ST70 upgrade mod work with a cathode biased EL34 power stage? thanx again
