Review CORNELL DUBILIER Black Cat .1 Mfd 400v Capacitors Vtg Guitar Audio Tube Amplifier Dubi

The Cornell Dubilier Electronics P Kummerly-Foster model PKM-4P1 is a premium quality capacitor specifically designed for use in vintage guitar audio tube amplifiers requiring a 400V capacitor with a voltage rating of 450V DC. This capacitor is manufactured by Cornell Dubilier, a leading supplier of electrolytic capacitors known for their high-performance and long-lasting products.

The PKM-4P1 capacitor is a radial lead, electrolytic capacitor with a total capacity of 4,700 F. It is designed to provide superior capacitance and energy storage for guitar amplifier circuits, ensuring optimal performance and tone. The capacitor is rated for a working voltage of 450V DC, making it suitable for use in high-voltage tube amplifier circuits.

The PKM-4P1 capacitor is built with a robust, thick aluminum foil electrode that offers excellent stability and reliability, even during long-term use. The capacitor also features a high-quality, porcelain case that provides excellent electrical insulation and mechanical strength. The case is also vented, allowing for safe dissipation of any internal gas pressure that may build up during operation.

One of the standout features of the PKM-4P1 capacitor is its low Equivalent Series Resistance (ESR). This low ESR ensures that the capacitor can deliver maximum current and power to the amplifier circuit, resulting in a more responsive and dynamic tone. The capacitor is also rated for a low leakage current, ensuring that it maintains its charge over long periods of time and does not impact the performance of the amplifier circuit.

The PKM-4P1 capacitor is a vintage-style capacitor that is highly sought after by guitar amplifier enthusiasts and restorers. Its high-quality construction, superior performance specifications, and classic design make it an ideal choice for use in vintage guitar tube amplifiers. Whether you are building a new amplifier from scratch or restoring an old one, the Cornell Dubilier Electronics P Kummerly-Foster model PKM-4P1 capacitor is an essential component that will help you achieve the best possible tone and performance from your amplifier.
