Sprague - 103P605 - Capacitor.
This is a high voltage paper-in-oil (PIO) glass sealed capacitor. Hermetic sealing keeps oil from leaking out and provides protection from ingress of moisture to ensure long life. Vitamin Q Capacitors are sought after because the oil that they are made from gives it a warm tone.
Capacitance: 0.10uF
Voltage/Current Ratings: 100V 10Amp.
Oil Type: Vitamin Q using polymerized impregnation fluid.
Threaded Vertical Mount, with Solder Terminals.
Dimensions: 0.375 inch D x 0.902 inch high.
Overall with terminals 1.748 inch.

Applications: Top choice for vintage-style tone in printed circuit board amps where space and size are considerations. May also be used in other guitar amplifiers and guitar tone control circuits.
For Gibson’s guitars, Orange Drop capacitors provide the stability and precision—therefore, consistent tone—that professionals expect. Other precision capacitors would be suitable, but Orange Drop capacitors have a well-deserved reputation for quality that has proven itself for close to half a century. With a track record like that, Orange Drop capacitors were consistent with Gibson’s intention to make the 2014 line of guitars and basses the finest musical instruments Gibson has ever produced.

ELECTRO CAP - 386-1059-000 - F500B305K - 3uF 100V Polypropylene RadialIN STOCK - MORE THAN 500 READY TO SHIP!ELECTRO CAP - 386-1059-000 - F500B305K- 3uF 100V Polypropylene Radial Capacitor
Polypropylene capacitors are designed for general purpose filtering applications. Their stability and low
loss characteristics make them an excelllent choice for blocking, filtering, bypassing, coupling and decoupling applications.A crossover serves as a filter that blocks out unwanted frequencies to a speaker or group of speakers. This is extremely useful because it allows us to specifically send each speaker the group of frequencies that it will play most efficiently and effectively.
Bypass capacitors are usually sized by convention or typical values. For example, common values are 1µF and 0.1µF. In the simplest terms, the larger value handles the lower frequencies and high current issues while the smaller value handles higher frequencies.Paraffin Wax
