The board has a 20x10 grid of pads and easily fits into 1590BB style enclosures and larger vintage-style fuzz enclosures. Each square pad is HASL coated making soldering easier than most protoboards and also ensures a long shelf life. Features:

• High-quality 1.6mm FR4 glass-epoxy circuit board
• 1oz/ft2 copper weight
• HASL coated square shaped pads
• 20 x 10 holes
• 3.04” x 1.55”

Prototyping circuit board with a standard long strip pattern where tracks run the length of the board. The long tracks are convenient for power and ground rails, and for signal buses. Strips can be cut as needed to make smaller tracks and circuit pads and the board has 0.1" hole spacing for DIP integrated circuits/ headers as well as other parts. Higher quality than traditional stripboard, the holes are drilled, not punched.

Prototyping circuit board that has a general purpose pad-per-hole pattern making it great for general purpose analog and digital use. It is a double-sided board with plated holes, which allows components to be easily 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. An anti-tarnish coating protects the copper for a long shelf-life and provides easy soldering.

LT1054 switched-capacitor voltage converter with regulator in an 8 pin DIP package. The LT1054 device is a bipolar, switched-capacitor voltage converter with regulator. It provides higher output current and significantly lower voltage losses than previously available converters. An adaptive-switch drive scheme optimizes efficiency over a wide range of output currents. Total voltage drop at 100-mA output current typically is 1.1 V. This applies to the full supply-voltage range of 3.5 V to 15 V. Quiescent current typically is 2.5 mA. The LT1054 also provides regulation, a feature previously not available in switched-capacitor voltage converters. By adding an external resistive divider, a regulated output can be obtained. This output is regulated against changes in both input voltage and output current. The LT1054 can also shut down by grounding the feedback terminal.

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.

The LM13700 series consists of two current controlled transconductance amplifiers, each with differential inputs and a push-pull output. The two amplifiers share common supplies but otherwise operate independently. Linearizing diodes are provided at the inputs to reduce distortion and allow higher input levels. The result is a 10-dB signal-to-noise improvement referenced to 0.5 percent THD. High impedance buffers are provided which are especially designed to complement the dynamic range of the amplifiers. The output buffers of the LM13700 differ from those of the LM13600 in that their input bias currents (and thus their output DC levels) are independent of IABC.
