Two of the prongs on each of my Sovtek 2A3 tubes are larger and two are smaller. The socket holes however do not appear to be of different sizes. The pictures in the manual don't seem to clarify much-- it's hard to tell, but it LOOKS like two maybe larger holes are towards the bottom in one picture, and towards the right in the other. I am confused and want to be sure I get the right pin in the right socket and get the sockets oriented so that the right pin is in the same place for both. Can someone clarify? Would it matter if my sockets were rotated differently as long as I got (what look like) larger pins in larger holes? (But then from the underside I'm thinking nothing would be in the right rotation, complicating construction.) Thanks sincerely for any help,
