Overview
The Visaton 5881 is a beam power tube designed for audio amplifier applications. It features an octal base (Int.Octal, IO K8A) and operates with a filament voltage of 6.3 Volts at 0.9 Amperes using indirect heating compatible with AC or DC supply. The component is functionally identical to the 6L6WGB specification.
Feature Summary
- Utilizes an octal base configuration for secure mechanical and electrical connection
- Supports indirect filament heating compatible with both AC and DC power sources
- Functions as a beam power tube suitable for high-fidelity audio output stages
Applications
- Audio amplifier construction
- Vacuum tube equipment maintenance
- Hi-Fi system restoration
Procurement Notes
Verify the specific manufacturer origin when sourcing this component, as it may be produced by various authorized vendors under the same technical designation. Confirm that the physical base type matches the Int.Octal K8A standard required for your chassis. Ensure the replacement unit meets the 6.3V / 0.9A filament specifications to guarantee proper operation within the intended circuit design without modification.
Selection Notes
Select this component based on its equivalence to the 6L6WGB standard for direct functional replacement in compatible circuits. Consider the availability of variants such as the 5881WXT if slight parameter differences are acceptable. Prioritize units that explicitly state compliance with the original GE Essential Characteristics documentation to ensure performance consistency in critical audio applications.
Part Context
This part belongs to the category of beam power tubes, historically significant in vacuum tube electronics. The 5881 designation represents a standardized form factor and electrical profile widely adopted in mid-20th-century audio equipment. Its continued relevance lies in its ability to provide robust power amplification characteristics within traditional tube amplifier architectures.
Replacement Considerations
The 5881WXT is listed as a normally replaceable variant with slightly different characteristics. Direct substitution with the 6L6WGB is confirmed due to identical status.
