High performance, ultrafast diodes. Improve efficiency, reduce noise, allow higher frequency operation.
$2.75 Diode Thyristor - Peavey, SBS 14 Bidirectional, 8V, TO-92 Case Designed for full-wave triggering in Triac phase control circuits, half-wave SCR triggering application and as voltage level detectors. Used in most Peavey linear power amplifier designs through 2000 including CS/M/DECA series power amps, IPA300, and all models using 402/602/304S/204S power modules. • Low Switching Voltage — 8 Volts Typical • Uniform Characteristics in Each Direction • Low On-State Voltage — 1.7 Volts Maximum • Low Off-State Current — 0.1 mA Maximum$1.50
Diode - Fast Recovery, 1A, 600V, 1N4937
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.
$0.20 Diode - Hexfred, 16A, 600V High performance, ultrafast diodes. Improve efficiency, reduce noise, allow higher frequency operation.$2.92

Diode - 1N5817, Schottky, High Switching Speed
Schottky diode with low forward voltage drop and high switching speeds.
$0.10 Diode - small signal fast switching, 1N4148A A semiconductor device which passes current in the forward direction(from anode to cathode), and blocks current in the opposite direction. For extreme fast switches.$0.50
Diode - 1N34A Germanium
The 1N34A Germanium diode is an old standby in electronics. Widely used for detecting the rectifying efficiency or for switching on a radio, TV or stereo etc.
$1.75 Switch - Vibrato LDR, for Fender® Amps Optocoupler. Vibrato LDR for Fender Amps. Fix the dead LDR-style tremolo on your vintage Fender amps as well as others. • Non-polarized optical side is indicated by silver dot and slightly longer leads • Resistive side is indicated only by slightly shorter leads$8.95
Diode - Zener, 1W, 1N4741A, 1N4748A
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.
