I've upgraded to one of Ivan's newer transformer pcbs so this is now surplus. It has 1:4 transformers on board, and was originally configured with I/V resistors on the output across the secondaries but on advice from Ivan I moved the I/V resistors on the input side, across the primaries (hence them being soldered under the board), and took the opportunity to upgrade them to vishay foil types.
