Fixing a Hohner JT60 (updating electronics)

The other part of my JT60 that needed work was the volume control and one of the tone controls - both potentiometers needed replacing. The component list I came up with was:

  • Tone: 2x A250kΩ mini pots 15mm height The A stands for Audio.
  • Volume: B250kΩ mini pots 15mm height The B indicates linear.
  • Switch: DECO T867-0061.
  • Pickups: 3x GS1S - middle one with yellow wire (RWRP).

The electronics look like the following pictures:

I was unable to find a circuit diagram on-line. This is the wiring schematic for my JT60:
