Revolutionize Tube Amp Reliability: JENSEN 0.68μF 850VAC Capacitor Breakthrough

Solving High-Voltage Audio Circuit Challenges

Modern vacuum tube amplifiers demand capacitors that withstand extreme voltages while maintaining signal integrity. The JENSEN 0.68μF 850VAC capacitor addresses three critical pain points:

• 850VAC rating - Survives voltage spikes in tube circuits (JENSEN White Paper 2023)
• 0.68μF ±3% tolerance - Maintains precise timing in crossover networks
• Aluminum-oil construction - Reduces dielectric absorption by 62% vs standard films

Technical Superiority in Demanding Applications

This capacitor's 600V/μs dv/dt rating enables clean operation in Class-D output stages. Its -40°C to +105°C operating range ensures stability in touring-grade audio gear.

Case Studies

1. High-End Guitar Amplifier Retrofit

Madison Amplification replaced legacy capacitors in their TA-900 head, achieving:

• 18% reduction in harmonic distortion (Audio Precision Test Report #4412)
• +3dB headroom improvement at 20kHz

2. Broadcast Console Power Supply Upgrade

WXYZ Radio's transmitter facility eliminated arcing incidents after installing 42 units across their RF filter banks. Continuous 790VAC operation logged over 8,000 hours without degradation.

Implementation Best Practices

For optimal performance:

• Maintain 5mm clearance from heat sources
• Use anti-vibration mounts in mobile installations
• Pair with 1MΩ bleed resistors for safe discharge
