High quality non-latching relays from the Panasonic TQ series. These 5 volt relays are commonly used in pedals for true bypass switching. Relay switching can allow for a variety of options on pedal builds. Different footswitch modes can be obtained using the same momentary footswitch. Stereo switching using a standard footswitch is another possible option. Features:

• Compact low profile size
• Standard DIL spacing for easy PCB use and breadboard compatibility
• Non-Latching
• Single Coil
• 5V Coil Voltage

For a latching version, please see P-RP-TQ2-L-5V.

Surface mount MMBFJ201 JFET. Commonly used in place of the discontinued through-hole J201. These JFETs can be found in many effects pedals, synthesizers, and other projects. The MMBFJ201 is an N-Channel general purpose amplifier JFET. This device is designed primarily for low level audio and general purpose applications with high impedance signal sources.

Stripboard made with a phenolic substrate. Phenolic boards are found in many vintage electronics before the use of fiberglass became common. This stripboard features 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 40 x 20 holes (20 strips). Each strip is surface treated making soldering easier than most protoboards and also ensures a long shelf life. Features: High-quality 1.6mm phenolic circuit board Corrosion resistant, surface treated copper strips 40 x 20 holes (20 strips) 6.14” x 3.15” Looking for projects? See our Wide Stripboard projects in our Pedal Layouts & Build Guides section for ideas.

Eight conductor Flexstrip ribbons cables. These ribbons feature a nomex insulator so there are no melting issues when soldering. Unlike typical ribbon cables, the wires are designed to distribute the stress of the bend and vibrations throughout the entire cable rather than directly on the solder joints. These cables are a great choice for PCB to PCB connections in pedals, synths, and other electronics. The spacing is .1" (2.54mm).

LM358H dual op amp in an 8-pin TO-99 package. The LM358H series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, dc gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems.
