    On the Bassman Micro LTP layout diagram you find the quote above on v4 Power Tube. It also shows a 6.3v center tap connected to the Power Tube Cathode resistor as well as 2 100 ohm resistors on the power tube.

    I do not find the 2 100 ohm resistors on the schematic or the 6.3v center tap on the PT on the schematic.

    I am using the recommended Hammond 270 AX, but I am unsure of which components apply to this part of the circuit for me.

    What should I include in the circuit? Thanks in advance.

    To be clear, there is no filament center tap on the 270AX, therefore you'll need the artificial CT. @Tom Kamphuys shared the schematic as it applies to you.

    If your power transformer has a 6.3v center tap then I recommend you use it. If it doesn't then add an artificial center tap.
