Transistor - AS394CH, Matched Pair, Alfa, TO5-8 case, NPN
The AS394CH is a junction isolated ultra well-matched monolithic NPN transistor pair with an order of magnitude improvement in matching over conventional transistor pairs. Electrical characteristics of these devices such as drift versus initial offset voltage, noise, and the exponential relationship of base-emitter voltage to collector current closely approach those of a theoretical transistor. Extrinsic base and emitter resistances are very low, giving very low noise and operating over a wide current range. To guarantee long term stability of matching parameters, internal clamp diodes have been added across the emitter-base junction of each transistor. These prevent degradation due to reverse biased emitter current, the most common cause of field failures in matched devices.

Transistor - 2N321, Germanium, TO-5 case, PNP
2N321 PNP germanium transistors. The 2N321 is a popular PNP for fuzz pedals and other effects. This transistor is in a TO-5 package with long leads commonly found on germanium transistors.

PCB - Vintage Style Circuit Board, HS Treble Booster, Phenolic Board w/ mount
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.

PCB - Vintage Style Circuit Board, Zonk II, Phenolic Board w/ mount
Zonk II 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 Zonk II pedal. The board is styled after the version that featured silicon transistors and a printed circuit rather than a stripboard construction. It is actually a cut down version of the Shatterbox PCB using only the fuzz side of that pedal. 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 screws.
