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 20x10 grid (10 strips) and easily fits into 1590BB style enclosures and larger vintage-style fuzz enclosures. Each strip is gold coated making soldering easier than most protoboards and also ensures a long shelf life. Features:

• High-quality 1.6mm phenolic circuit board
• Gold coated strips
• 20 x 10 holes (10 strips)
• 3.04” x 1.55”

OPA2134 SoundPlus™ Audio dual op-amp with low distortion, low noise and precision. The OPA2134 are ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. A true FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. This, in combination with high output drive capability and excellent DC performance, allows for use in a wide variety of demanding applications. In addition, the OPA2134 has a wide output swing, to within 1 V of the rails, allowing increased headroom and making it ideal for use in any audio circuit. The OPA2134 SoundPlus™ audio operational amplifiers are easy to use and free from phase-inversion and the overload problems often found in common FET-input operational amplifiers. They can be operated from ±2.5-V to ±18-V power supplies.

Plastic wing knobs with set screws and brass insert. These knobs are a close match for the classic knobs used on Marconi radios and Neve consoles. They feature an inlay indicator line. The grip diameter is 0.693 inches with a 1 inch clear skirt. Fits ¼” (6.35mm) pot shafts.

Holder for mounting LEDs to panels.

The BC558 is a silicon general purpose PNP transistor in a TO-92 package. The BC558’s typical applications include signal processing, amplification, and switching.

600V solid wire. UL style 1015, rated to 105 degrees C. Perfect for new projects, rewiring electrical equipment, or use in breadboards, perfboard, and veroboard/stripboard.

The PadBoard-2 prototyping circuit board has a general purpose pad-per-hole pattern which is good for analog and digital use. It is a double-sided board with plated holes, which allows components to be soldered to either side of the board. A square pad is provided every 5th hole, which makes it easy to align components on the top and bottom of the board. Features

• Pad-per-hole prototyping board with plated-thru holes. A square pad every 5th hole makes it easy to align components on top and bottom.
• Double-sided high-quality FR4 glass-epoxy circuit board with plated holes. Components can be soldered to either side.
• 1oz/ft2 copper with an anti-tarnish coating for easy soldering. Lead free and RoHS compatible.
• 31 x 39 holes, 0.037" holes are drilled on 0.1" (2.54mm) centers. Four 0.125” mounting holes.
• Size2 = 100 x 80mm (3.94 x 3.15in), 1/16" thick (1.6mm)
