Dust Cover - Plastic covering for 16mm Potentiometers, Clear
Clear dust cover for use with 16mm potentiometers. These covers slide over the back of the pot covering the holes and gaps to help prevent dust from accumulating inside avoiding potential repairs and replacing down the road. These covers are a great choice for tight builds to help insulate the PCB or other parts from the backs of potentiometers. The dust cover is made of clear hard plastic and is easy to install on Alpha 16mm pots.

Diode - Zener, 5 Watt, ±5% tolerance
5W zener diodes that are great for use in tube amps. These are commonly used to drop B+ voltages for tube modification compatibility or to create low power modes for the amp. A zener is 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.

Op-Amp - TL084, Quad, Wide Bandwidth, JFET-input, 14-Pin DIP
TL084 quad op amp in a 14-pin DIP package. These devices are low cost, high speed, dual JFET input operational amplifiers with an internally trimmed input offset voltage ( BI-FET II™ technology). They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents. The TL082 is pin compatible with the standard LM1558 allowing designers to immediately upgrade the overall performance of existing LM1558 and most LM358 designs. These amplifiers may be used in applications such as high speed integrators, fast D/A converters, sample and hold circuits and many other circuits requiring low input offset voltage, low input bias current, high input impedance, high slew rate and wide bandwidth.
