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:
