    That reminds me that I really need to get a scope, haven't used one since the 70s.

    sorry you 're right, I was thinking of cathode poisoning.

    I have another question:
    If I go SS was thinking of making it a full wave bridge rectifier, if so does the center tap on the tranny still need to be grounded?

    That won't work with your current secondary configuration. A full wave bridge is grounded at the negative side of the bridge and thus uses the full voltage across the transformer secondary. So if you do were to do this, it would double your output voltage! Best to keep it full wave center tap.

    and if you used a bridge and grounded the center tap, you'd be shorting half of the transformer, so that doesn't work either.

    Double voltage, half current, or near enough when using a full wave bridge vs full wave center tap.

    I decided to stick with the tube rectifier, this is the result. It works great. Making a new top plate for the phono pre, don't need all of those holes anymore.
