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:

Fixing a Hohner Jt60 (new tremolo block)

I've had a Hohner JT60 "Hollywood" guitar for a long while. It's unusual in that it has an ATN (Advanced Tonal Network) (the link is to a discussion in German on the potential circuit in the ATN). The idea is that you can obtain a wide range of tones from combinations of the volume and tone controls.

The guitar needed some work. Opening it up I found that the tremolo block had cracked and the springs had grown weak - as shown in the picture.

So the first fix was to replace the tremolo block with a Musiclily block that fitted the guitar. The dimensions of this tremolo are shown in the diagram - and it fits very well.
