Constructors should refer to the Component Overlays along with,
the Bill of Materials for the current value of all components, and
the General Construction Notes for general PCB assembly guidelines.

1. Construct the 2x Jack Swith sub-assemblies (3D Model)
2. Fit the LED lens to the front panel
3. Mount all components on to the PCB except for the 2x Jack Switch sub-assemblies and the LED
4. Install the 2x Jack Carrier sub-assemblies but do not solder
5. Offer the assembly up to the front panel and secure using the supplied nuts and washers
6. Solder the sub-assemblies in to place
7. Form the LED and install taking note of the orientation

Modification:-

Fit R18 between the centre pad of P4 and the left-hand pad of C7 (-12V) and should be applied to the underside of the PCB.

The PCB has been factory modified with the track running to the centre pad of P4 (on the underside of the PCB) having been cut.
