The TubeCap® combines a high degree of dielectric strength and low residual inductivity with a very compact form of construction. It has been developed as a high-quality technical alternative to high-voltage electrolytic capacitors and is thus ideally suited to use in tube amplifiers power supplies.

The advantages over electrolytic capacitors are:

• Lower ESR and lower residual inductivity
• No drying out; therefore longer service life
• Excellent Self-healing properties
• More compact form of construction
• There is no series connection necessary
