    I am stuffing a set of octal mark3 boards. I see the holes to jumper on one of the 6sn7, but not the other. Are both 6sn7 tubes jumpered with p1,p2?
    Thanks

    I went over the schematic and just jumpered one of the 6sn7 since the jumper positions were on the circuit board. One of the diagrams in the instructions showed both 6sn7 to be jumpered p1 to p2.
    Thanks

    Hi -- Only one 6SN7 tube is jumpered; just checked my Mk3 Octal boards and it is the tube nearest the RCA Input Jack. Have fun! Stew
