Op-Amp - NJM4580L, Dual, Audio, 8-Pin SIP
NJM4580L dual op amp from JRC in a SIP8 package. The NJM4580L is the same as the DIP NJM4580 (JRC4580) otherwise. The SIP version is a great replacement for dual op amps in vintage circuits as well as a space saving package for some PCB layouts. The NJM4580 is a dual operational amplifier, specially designed for improving the tone control, which is most suitable for the audio application. Featuring noiseless, higher gain bandwidth, high output current and low distortion ratio, and it is most suitable not only for acoustic electronic parts of audio pre-amp and active filter, but also for the industrial measurement tools.

PCB - Vintage Style Circuit Board, HS Treble Booster, Phenolic Board w/ mount
HS Treble Booster style circuit board made with a phenolic substrate for an even closer match to the vintage production boards. Phenolic boards are found in many vintage electronics before the use of fiberglass became common. This board is a recreation of the circuit board found in the Hornby Skewes ‘Treble Booster’ pedal. The board is styled after a version of the silicon Treble Booster but can be used for the germanium version as well. When drawing the layout, original boards were closely referenced to ensure a proper match and fit. The copper traces have a surface treatment providing protection from corrosion. This board includes a blank mounting PCB. This PCB sits directly beneath the main board to mount it directly to the enclosure using a screw. For a detailed drawing of the parts and connections originally used on this board, please see the layout drawing linked below.
