from each other and I also added a piece of automotive gasket material to support the tube so it won’t vibrate against the PCB. Below is a diagram to help you identify the leads before you put them in the holes. For now, if you put the leads in the holes, you don’t need to solder the two leads required for the tube heaters because they should make enough contact to light up the heater if it is oriented correctly. If it doesn’t light up, you can easily remove and re-orient the leads. I learned that after soldering it in and trying to remove it the first time. So, the power supply and the preamp board should be completely populated and ready to go before you solder this tube in place. The submini tube is soldered on the non-component side of the board. The same side as the pots and on-board switches are. The holes are numbered 1-8, but on the 2.0 version of the board, the numbers are on the component side, so as you look at the numbers, flip it over to the non-component side and mark with a marker, or nail polish the number one hole. The numbers do not directly correspond to the numbers of the bigger socket holes for the Noval socket.
