Low-profile adhesive standoffs with a 0.180" standoff height that securely attaches your PCB to a flat surface. The post inserts into a 0.125” mounting hole and includes a locking tab that secures the PCB when inserted. It can be used with 1/16” or 1/32” thick PCBs. The 0.6 x 0.6” square base is offset to allow the base to be underneath the board when the mounting hole is close to the PCB edge and the offset base provides a large sticking surface while permitting the PCB to be mounted in tight spaces or close to walls. This can be useful when working with small enclosures. High-quality 3M™ brand double-sided tape secures the standoff to a flat surface. These standoffs are available in packs of 8, 24, or 100 pieces Features:

• Low profile 0.180" standoff height.
• Offset base allows use when holes are close to the PCB edge.

High-quality solder lug linear taper 16mm pots from Gorva Design. Gorva Design left no boxes unchecked when engineering their potentiometer lineup. Every element was carefully designed to offer builders an exceptional potentiometer with high durability and tight tolerances. Gorva potentiometers are made with stompboxes in mind but offer the same advantages to amplifiers, synthesizers, studio equipment and other electronics.

• Solder lug / panel mount
• Linear taper

2N527 PNP germanium transistors. The 2N527 is a popular PNP for fuzz pedals and other effects. It can be found in modern classics such as the Sunface and Benson Fuzz. This transistor is in a TO-5 package with long leads commonly found on germanium transistors.

BC238B NPN transistor in a TO-92 package. The BC238 is used in a variety of vintage pedals such as the Schaller Fuzz, a version of the Brian May treble boost,and later Jen / Tonebender fuzz pedals. The BC238B is a variant of the BC108B and works well in other classic fuzz pedals such as Fuzz Face and Big Muff builds.

Stripboard featuring a 0.15” vintage spacing. This spacing is great for vintage-style builds and more easily accommodates axial capacitors and other larger sized vintage parts like resistors and transistors. The board has a 20x10 grid (10 strips) and easily fits into 1590BB style enclosures and larger vintage-style fuzz enclosures. Each strip is HASL coated making soldering easier than most protoboards and also ensures a long shelf life. Features:

1N4742A 12V zener diode in a DO-41 package. A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.
