I think I figured it out. I was looking at the TwoQuiet manual when I tested the voltages for Terminals 1 and 11. This was after I added the 5w 22ohm and 270ohm wirewound resistors between 31-39. By adding these resistors in parallel with the existing resistors, this should increase the voltage because the voltage drop will be less on those resistors. Am I correct?
My other question what does the B+ Raw mean in the output manual upgrade?
