Integrated Circuit - LM386N-1/NOPB
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.

Op-Amp - Orange, Dual Discrete
The Dual Discrete op-amp is specially designed for audio and is among the most musical sounding dual discrete op-amps out there. It is available in DIP 8 format and can be used in any CD player, DAC, or preamplifier that currently runs DIP 8 based IC dual op-amp types.
The overall soundstage and transient detail will be greatly improved when used in pretty much all audio equipment that it can physically be fitted to. It has a very low noise Jfet front end so it can run with input impedances above 1M Ohms if needed. It can replace the following, provided the equipment it’s being used in has 22mm of height clearance and 5mm side clearance (per side).
Please check that the PSU can supply the extra current needed, especially if replacing more than one existing IC op-amp with our op-amp as with all discrete types, they do draw more current.
