OptocouplerOptocouplers transfer electrical signals between isolated circuits through light, allowing isolation of high voltages from lower voltages.
Optocoupler - VTL5C1, Vactrol, for Channel Switching
VTL5C1 vactrols for use in amplifiers, effect pedals, synthesizers and more. The VTL5C1 was commonly used for channel switching circuits in amps made by Crate and others.
Optocoupler - Vactec, VTL5C1, Vactrol, New Old Stock
New old stock Vactec VTL5C1 vactrols from Perkin Elmer Optoelectronics. These premium vactrols are a great choice for use in phasers, compressors, tremolos, and synth modules such as low-pass gates. They are also used in switching circuits in amplifiers. Limited quantities are available.
Audio Power Amplifier - LM386N-1, Low Voltage
LM386 Low Voltage Audio Power Amplifier The LM386 is a mono low voltage amplifier that can be used in a variety of applications. It can drive loads from 4 Ω to 32 Ω. The gain is internally set to 20 but it can be modified from 20 to 200 by placing a resistor and capacitor between pins 1 and 8. As this is an Op Amp it can be used in different configurations to fit in several applications. The internal gain setting resistor allows the LM386 to be used in a very low part count system. In addition a series resistor can be placed between pins 1 and 5 to modify the gain and frequency response for specific applications. These are found in many small audio amplifiers and even tiny pedal sized guitar amplifiers! There are tons of possibilities for this little Op Amp.
Integrated Circuit - Fender®, Power Amp PC1188H
PC 1188H Power Amp - Fender The PC1188H is a monolithic integrated circuit and a power amplifier designed for Hi-Fi audio sets. The PC1188H can provide 20W (typical) to 8 ohms at 1% T.H.D. and +/- 22V supply voltage. Features:
- High output power
- Low distortion
- Wide frequency bandwidth
- A muting function which eliminates pop on noise and the thermal and the over current protection circuit
