ECC85 6AQ8

The ECC85 and 6AQ8 are different designations for the same vacuum tube. The ECC85 is the European designation, and the 6AQ8 is the American designation for a specific double triode tube. Here are some key specifications for this tube:

• Type: Double Triode
• Filament Voltage: 6.3 V
• Filament Current: 0.3 A
• Plate Voltage: 330 V
• Plate Current: 8 mA
• Amplification Factor (Mu): Approximately 33

These tubes are often used in audio applications, particularly in the preamplifier stages of audio amplifiers and other electronic devices. As with other vacuum tubes, the ECC85/6AQ8 has specific electrical characteristics, and its application will depend on the requirements of the circuit in which it is used.

It’s always a good practice to consult the datasheet for the specific tube and follow the manufacturer’s recommendations for optimal performance. Additionally, since vacuum tubes are electronic components that have largely been replaced by solid-state alternatives, availability may be limited, and vintage or NOS (New Old Stock) tubes may be used in some cases.
