I noticed that my rev 1.1 pcbs have some jumper markings next to the tube, on the side
where the 330K resistor is. I can't quite tell how they should be populated. Could you
explain?
Install the 330k in the position marked "330k" AND the jumper in the
position marked with a solid line,
OR
Install the 330k in the position with no value specified AND the jumper in
the position marked with a dashed line.
Pins 1 and 2 of the tube can be swapped by installing them in the two holes
next to the ones marked 1 and 2 (saves getting the wires crossed).
