Would check to see if the have plate voltage on the 6J5 driver tube. May have a bad driver transformer, hope not. If you have plate voltage on both 6L6's plates that rules out the primary of the opt. And if you have bias on the control grids of both 6L6's that rules out the secondary of the driver transformer.
