I built the Tube Depot 5E3 Deluxe kit, it works fine but I think it's not quite right. The volume controls seem to have an effect on each other even when not jumpered. Also, volume drops off between 10 and 12. So, I decided to buy an assembled PTP eyelet board from Mojotone. My plan is to take out the PCB and drop the PTP Mojotone board into the Tube Depot chassis. But, when I compared the wiring diagrams from Mojotone and Weber I saw at least one difference in regards to the way that the power tubes are wired up. Tube Depot takes a lead to both #1 terminals and connect a resistor from the #1 and #4 terminals of each 6V6 socket. Weber and Mojotone seem to link the #4 terminals and ignore the #1 terminals and omit the resistor. My best guess is that I need to take the resistor off of the socket and take the lead from the board to the #4 terminals when I drop in the Mojotone board. I'm hoping that will not be a problem. And I'm assuming that the #1 terminals end up empty. Can anyone tell me why Tube Depot put those resistors there and why other builders did not?
