The bug resistor and the 4meg pot are wired in parallel. According to the spreadsheet that I've put together that calculates the various resistance for various conditions of the pot and the resistor, I think I can use a 5 meg resistor (those seem to be available) and I doubt that you would be able to tell the difference.
In any event, I'll rummage through my stuff. If I can find the power transformer that I think I have to power the 12ax7, I'll start the process of assembling what I need to build the test rig.
