Dual Operational Amplifier. The NJM4558 (JRC4558) integrated circuit is a dual high-gain operational amplifier internally compensated and constructed on a single silicon chip using an advanced epitaxial process. Combining the features of the NJM741 with the close parameter matching and tracking of a dual device on a monolithic chip results in unique performance characteristics. Excellent channel separation allows the use of the dual device in single NJM741 operational amplifier applications providing density. It is especially well suited for applications in differential-in, differential-out as well as in potentiometric amplifiers and where gain and phase matched channels are mandatory.

Used these as replacements in a matching pair of old 1980's Marshall 5010 Master Lead Combo amps. Of course, the originals were soldered directly to the PCB, so I put in a socket and slipped these baby's right in. My ears are old, so I can't tell any significant difference in tone (why would you?), but I will say the sudden burst of gain & noise at 9+ preamp volume seems slightly less? Very satisfied with how easy it was to make the switch.
