Eli , I believe I have an old Mark I board by Sheldon Stokes with EF86 pentode input stage and 12au7 driver. I exchanged 12au7 for 12BH7 and 0,22 orange drops (715P) for Hovland caps and the amp became little more articulate. I will change EF86 grid decoupling 0.1 orange drop cap to Vit Q PIO (Maybe experiment little with value ) and try some resistor changes mixing some carbons and Mills in. Jim lives nearby (well almost , 30 miles away:) Warm regards, W
