Jantzen Amber Z-Cap C&B Copper Foil Capacitors

The Jantzen Audio Amber Z-Cap “C&B” is a 630V DC-rated version of Jantzen’s pure copper foil capacitors, specifically designed for use as a coupling capacitor upgrade in tube and certain solid-state amplifiers, as well as for use in passive crossovers as a bypass capacitor for tweeter circuits.

The “C&B” stands for “Coupling and Bypass”.

Like the larger-value Amber Z-Caps, the Amber Z-Cap C&B is a super high-end pure copper foil capacitor. The sonic character of copper foil is best described as delivering an exceptionally neutral and natural presentation of vocals and instruments. This is combined with enhanced transparency and a higher level of detail retrieval compared to many other capacitor types.

Compared to the larger-value Amber Z-Caps, the Amber Z-Cap C&B is available in smaller capacitance values and features a thicker dielectric insulation, allowing for a 630V DC rating. This gives the Amber Z-Cap C&B sufficient voltage handling for amplifier applications.

Jantzen created the Amber Z-Cap C&B as an excellent option for upgrading coupling and power supply capacitors in tube (pre-amplifier) amplifiers and certain solid-state amplifiers. Its compact size is particularly beneficial where space inside amplifiers is limited.

In addition, adding a smaller-value Amber Z-Cap C&B capacitor (for example, 0.01μF) as a bypass capacitor in parallel with a high-quality series capacitor in a tweeter circuit can further enhance transparency, detail, and overall musical refinement.

Features:

• Super high-end pure copper foil capacitors for upgrading coupling capacitors in tube amplifiers (pre-amp) and certain solid-state amplifiers
• High quality pure copper foil wound with high precision on specialized winding machinery
• Can also be used as a bypass capacitor in parallel to a high-quality series capacitor for the tweeter circuit on passive speaker crossovers
• Very compact in sizing compared to other 630 volt rated copper foil capacitors on the market, which makes a big difference for application in tight spacing of amplifiers
• For safety reasons and to eliminate the risk of short circuiting, the Amber Z-Caps C&B capacitors do not have the decorative anodized aluminum jackets (tubes) which are used on their larger value counterparts that are for use in passive speaker crossovers only.
