PAPER IN OIL PIO AUDIO CAPACITORS  for:
guitar tone upgrade K40Y- 9 / K40U- 9 

For example, 200 V 0.047 microfarads have great sound with the Gibson Strato Telecaster, 200 Volts / 0.033 microfarads are ideal for the P-90 Pickup. 

As with all K40Y9 capacitors, it can be used to solve various problems. Small containers are used as the tone capacitors, other caps as bypass or coupling caps. 

If you already have a SPRAGUE VITAMIN Q or Orange Drop, you must buy these K40Y-9 PIO capacitors.

K40Y-9 capacitors are a type of vintage audio capacitor that was manufactured in the former Soviet Union, in Ukraine by Epsilon Capacitor Plant  Odesa, , during the 1960's-1990's. These capacitors are known for their use in various audio equipment, including amplifiers, radios, and other electronic devices. They have gained a reputation among audiophiles and vintage audio enthusiasts for their unique characteristics and sonic qualities.

Here are some key features and details about K40Y-9 capacitors:

Paper-in-Oil Design: K40Y-9 capacitors are constructed using a paper-in-oil (PIO) design. This means that the capacitor's dielectric material is typically paper, and it is impregnated with oil to improve its performance and longevity. The use of oil helps to reduce heat generation and maintain stable capacitance values over time. Capacitor plates are made of aluminium foil.

Vintage Aesthetics: K40Y-9 capacitors are recognized for their distinctive appearance, often featuring a cylindrical metal can without or with colored paint and markings that indicate their capacitance and voltage rating. The colored paint on the capacitors can vary, with common colors being pink, orange, and grey.

Capacitance Values: These capacitors typically come in a range of capacitance values, in the range from 470 picofarads (pF) to 1 microfarad (uF). The exact capacitance value is usually indicated by markings on the capacitor's body.
