The AS301AH is Alfa’s version of the LM301A in an 8 pin TO5 package. The AS301A is a general purpose operational amplifier. This amplifier offers many features which make its application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, and freedom from oscillations and compensation with a single 30 pF capacitor. It has advantages over internally compensated amplifiers in that the frequency compensation can be tailored to the particular application. For example, in low frequency circuits it can be overcompensated for increased stability margin. Or the compensation can be optimized to give more than a factor of ten improvements in high frequency performance for most applications. In addition, the device provides better accuracy and lower noise in high impedance circuitry.

3PDT latching footswitch. LED ring requires a 11/16" mounting hole. Foot switch button set screw requires 1.5mm hex key.

Carling SPST latching On-Off footswitch. Used in Fender etc. Reverb/tremolo/channel switching pedals, (110-P).

4.72" x 3.70" x 2.1" (119mm x 94mm x 56mm) diecast aluminum enclosure. Equivalent to the Hammond 1590C enclosure. This enclosure is a taller version of the 1590BB allowing for more vertical space for larger projects.

Heavy duty SPST Off-(On) momentary switch made in Italy by ST Professional. Rated for 2A at 240V, these switches can be used in a wide range of applications. The body is made of PBT that is riveted to the bushing plate for a sturdy construction. The actuation force is lighter than similar Carling momentary switches and provides tactile and audible feedback so the switching action is apparent to the user. This version features standard solder lugs.

2 rows/6 lugs per row, 2 mounting holes. Board dimensions 3" x 1 ¼".

The pins also feature eyelets so hardwiring is an option in addition to the standard PCB mount.

• Rugged, diecast aluminum alloy (tough yet easy to machine), electronic instrument enclosure.
• Lap joint construction provides protection against access of dust and splashing water. Also provides for improved EMI/RFI shielding.
• Vibra finished for a smooth surface with no sharp edges.
• Four 6-32 x ½" machine screws secure lid - into tapped holes.
• Designed to meet IP54.
• Low side wall draft angle (2 degrees or less) for easy P.C.

1 row/12 lugs per row. 2 mounting holes. Board dimensions 5 ¼" x ½".

Genuine Dunlop replacement fuzz potentiometer for JDF2 Fuzz Face. 1 kΩ, linear, solid plastic shaft. Made In U.K.

Switchcraft ¼" Mono 2-Conductor Input Jack, Isolated Make Circuit (Type 13). Includes nut and washer

Painted phenolic knobs with a set screw and brass insert. These unique knobs closely match the colorful RCA style of knobs used on vintage test equipment, radios, studio consoles and other equipment. They are sometimes referred to as fester knobs. These classic knobs are painted to match the style of the original painted RCA knobs. The paint is a durable chip-resistant coating. The RCA style knobs feature an inlay indicator line. Fits ¼” (6.35mm) pot shafts.

• Height: 0.792 in. (20.1 mm)
• Diameter: 1.293 in. (33 mm)
• Fits ¼" shaft with set screw

Equivalent to Hammond P-H1590N1. Depending on the manufacturer, this enclosure is usually very similar to a 125B.
Measures 4.77" x 2.58" x 1.41". Add 0.16" to enclosure depth for lid.

All-metal solder spool stand with a large metal roller for a smooth reel out. This stand features a handle as well as an eyelet that holds the solder line in a static position for ease of use. Extremely useful for making your soldering jobs quick and easy!

The AS571D is Alfa’s version of the NE571 or SA571 in an SOIC package. AS571 is a versatile low cost dual gain control circuit in which either channel may be used as a dynamic range compressor or expandor. Each channel has a full-wave rectifier to detect the average value of the signal, a linearized temperature-compensated variable gain cell, and an operational amplifier. AS571 is well suited for use in VCA blocks, noise reduction systems, compandors/expanders ,etc. Features

• Complete compressor and expandor
• Temperature compensated
• Channel separation >86 dB
• Greater than 110 dB dynamic range
• Levels adjustable with external components
• Distortion may be trimmed out

Applications

• VCA
• High level limiter
• Low level expandor − noise gate
• Dynamic filters
• Dynamic noise reduction systems
