Among the earliest products known from Sound Projects Company is the K100 amplifier.  It is similar to the Troubadour amp in size, design and color.  It was probably built in the 1930’s.

    I am looking to rebuild this. also came with a DeArmond Tremolo mounted on the side.

    I’m having a sound projects 100 repaired but the guy is stuck on the resistor that sends power to the pre amp input circuit. Anyone know the values? There is 110 v current to the resistor and nothing on the other side.
