  • PI changes in blackface to silverface Deluxe Reverb

    Hey guys,
    On the silverface Deluxe reverb, a few of the resistor values and cap values got changed in the PI compared to the blackface.

    The plate resistors went from 100k, 100k to 85k, 100k. Two resistors before the grids went from 1M to 330K.

    Can someone explain what these changes were trying to accomplish, and if it make sense to revert this section back to blackface specs. I'm hoping to increase headroom on this amp.
Working...
