Good job Rob. What's it sound like? I am in the prelimary stage of doing a version of the ST35 also. Iplan on using a 6SL7 to 6SN7 front end4,, and a 6V6 output tube stage. Mine will also be monoblocks.
See, Rob is good example of how things should be! There... on the dining room table sits the amp! You finish your meal... Loosen your belt a notch, the women and children pick up the dishes, and you get right to work! Now THATS a man of the house!
