HS Treble Booster style circuit board made with a phenolic substrate for an even closer match to the vintage production boards. Phenolic boards are found in many vintage electronics before the use of fiberglass became common.

This board is a recreation of the circuit board found in the Hornby Skewes ‘Treble Booster’ pedal. The board is styled after a version of the silicon Treble Booster but can be used for the germanium version as well. When drawing the layout, original boards were closely referenced to ensure a proper match and fit. The copper traces have a surface treatment providing protection from corrosion.

This board includes a blank mounting PCB. This PCB sits directly beneath the main board to mount it directly to the enclosure using a screw. For a detailed drawing of the parts and connections originally used on this board, please see the layout drawing linked below.
