Key Specifications & Features
- Tube Type: Beam power tetrode with an octal (8-pin) base and an equipotential cathode. [1, 2]
- Power Dissipation: Rated at 85 watts for plate dissipation, allowing a pair of tubes to drive high-end hi-fi output stages exceeding 300 watts. [1, 2]
- Filament/Heater: Requires 6.3V nominal (6.0V–6.6V), drawing approximately 1.75A to 2.0A (around 1.9A–1.97A measured). [1, 2, 3]
- Physical Size: Features a distinctive, large-bulb envelope designed for high heat dissipation, measuring roughly 136 mm to 137 mm in height. [1, 2, 3]
- Compatibility: Often positioned as an upgrade or alternative to tubes like the KT88, KT120, or KT150, though amplifiers must have sufficient physical clearance inside the chassis and power/filament transformers capable of handling the higher heater current. [1, 2, 3]
Comparison of High-Output KT-Series Power Tubes
| Tube Model | Max Plate Dissipation | Typical Application / Notes |
|---|---|---|
| KT88 | ~42 Watts | Standard high-power audio pentode/tetrode, classic hi-fi and guitar amps |
| KT120 | ~60 Watts | Higher output extension, popular in modern high-wattage tube designs |
| KT150 | ~70 Watts | Egg-shaped bulb, high dynamic headroom and extended low-end response |
| Tung-Sol KT170 | 85 Watts | Maximum power in the series; heavy-duty bass definition and >300W stereo pair potential |
