I've mentioned the polarity of the caps a couple of times now.
The two electros, near as I can tell, (which is a bit hard because of the double sided board and black lacquered tracks) , both visually and metered, are wired as per my mud map diagram.
Pretty sure. One leg of the cap bank is direct to the input active trace.
The other end of the cap bank is connected to neutral input leg via one bank of diodes.
The X2 cap is connected the same but opposite. (to neutral input trace and then to active thru the diode bank on the active input trace)
