ST-70 boards require either 2x EF86 (or interchangeable), or 6AU6/EF94 (or interchangeable), depending on version, and one 12AU7/ECC82, 12BH7 or ECC99 tube. And now in our newest EF86 version you can run 6922 as well. This change really opened up the amp in our shop system. Our board has lots of tweeks and variations to try. Having these options gives the amp the flexability to sound great in many systems, and gives the user lots of sonic options. It also can be adapted to make a killer tube mic preamp. Mk3/Mk2 boards require 2 12AU7/ECC82 and one 12AU7/ECC82,12BH7 or ECC99 for each amplifier. All boards include a comprehensive manual on rebuilding & maintaining your Dynaco amplifier.
