    Hi guys, I think I've got this one sorted.

    I'm thinking the insertion of the reverb mixing resistors were causing some problems.
    Also converting the 220k/100k plate resistors back to the original schematic is working much better and finding the right valve to do the job is needed.
    The 5k trim is needed to find the sweat spot to make the trem function.

    On the schematic I have shown the grounding, this also has helped with some of the hum.

    The reverb is huge.
    And connecting it as shown on the schematic has worked well.

    Hi guys, Doing some hard thinking to get this one sorted.

    Adding another valve seems to be the only option.

    With some info from sluckey's 18w

    The 6av6 should do the job nicely, as the smaller heater draw will be less stress on the PT.
