      Hello Ted,

      how are you? Wish you well

      I have an Alice 828 MK1 and would like to modify it  so that I would be able to have a switch to turn the EQ on/off like in the MK2, stock the MK1 has the EQ always on the channels.

      Is it possible to modify the MK1 to have an On/off switch on the EQ? if so where do you advise on the schematic to cut the connections for the switch

      Thank you so much

      T

        It would be possible to add an EQ in/out switch, but there may be problems with levels.
        The top of the channel fader is fed by a 100uF cap. Switching the input of that from the output of the input amplifier should do the job, but I would advise against it because of probably unforseen level and stability problems.
        If anyone asks me to carry out that mod, the answer would be no!

          Here is the circuit diagram.
