    Concord Reverb Tank

    I have a reverb tank from a parts Concord that I'm wanting to put in a guitar amp. Its an Accutronic and I'm trying to find out if the circuit board on top that plugs into the tank is the amp for the reverb because that'll save me a lot of custom wiring if that's a preamp for the tank. Its on top of the tank the one end plugs into a connector that has the input and output of the tank and the connector on the other end has more than the 4 wires on the tank side. Is this the amp for the reverb?

      I did a search for Concorde service manual and found this. It looks like there is a module that is the reverb driver and preamp

        It is the tank driver and receiver circuit.
        Pins 4,5,and 8 are ground.
        Pin 3 25Vdc.
        Pin 6, 7, and 9 inputs.
        Pins 1 & 2 output.
        Takes about 1Vac at the input and has a pot on the board to adjust the output level.

              Don't forget to mount it in such a way that you can crash the springs for that unique "Reverb tank smash" sound effect
