Stltrains,
Thanks to RX8man who introduced the idea to add this to Joseph's preamp. Washers are used as a barrier between the board and the screw plate. In my set up, I have an isolation board which takes out subfrequency noise and under the tube board I floated it on three points and stabilized it with tape on each side.
I believe the washers can be supplied by Rx8man as well.

Victor, does the in-line AC filter serve as part of the grounding for the original AH preamp?
