Try taking out TX1 to see if this restores the correct voltages to TX2 as it could be TX1 is faulty or round the wrong way. Is the voltage being pulled down or are one of the feed resistors R9, R16 faulty leading to a lower voltage due to high resistance, might explain the higher DC voltage at the rectifier. If you haven't changed C5 try lifting one end in case it is leaky and pulling the rail voltage down.
