PCB and parts kit for the HS Treble Booster. This is based on the more common silicon version that used a 2N4061 transistor. This kit includes all of the resistors, and capacitors used on the included circuit board. A 2N4061 transistor is included. In addition to the PCB parts, a footswitch, jacks, battery snap, and ground lug are all included in this parts kit. Instead of the small slide switch used in originals, this includes a DPDT footswitch.

Note: Enclosure, battery, PCB mounting hardware, and wire are not included.

The Si Treble Booster premium parts kit includes the following high quality parts:

• Phenolic HS Treble Booster PCB
• Vishay PR02 Resistors
• Vishay BC Electrolytic Capacitor
• Vishay Roederstein MKT1813 & Mallory Film Capacitors
• Cliff Jacks
• Carling DPDT Footswitch
• Premium I-Style Battery Clip
• M3.5 Ground Lug

This build shown in the photos uses S-W3024TC-X-50 wire. This is a high quality wire with color options and features a top-coat of solder so no tinning is required.

The PCB is mounted with a 10mm M3 S-HS-M3-10 and S-HHN-M3 nut. This length works well in the Hammond 1590B3 enclosure but different lengths might work better depending on your enclosure choice.

The build is in a P-H1590B3 enclosure which has a very similar footprint to the original folded metal enclosures used. It is also wired for true-bypass. A drill guide for this enclosure along with a vintage wiring guide and true-bypass wiring guide can be found in the In the Specifications, Files, and Documents
