Has a Telefunken tube installed with an extra tube included. Downsizing and can't keep it. My loss is your gain.

Includes: carrying case, ntk power supply with power plug, 7 pin cable, shock mount (not original).

Works great and sounds beautiful.

The Rode NTK is a premium, large-diaphragm valve condenser microphone renowned for its smooth, tube-driven warmth and clarity. It features a hand-selected 6922 twin-triode vacuum tube, fixed cardioid polar pattern, and ultra-low self-noise. Key Characteristics of the NTK

• Warm, Intimate Tone: The tube architecture gives vocals and acoustic instruments a euphonic, analog sweetness without muddying the mix.
• High SPL Handling: It can handle up to \(158 \text{ dB}\) SPL, making it versatile enough to capture loud sources like guitar cabinets and drum overheads.
• Dedicated Power: Because it is a valve mic, it requires the included dedicated external power supply to operate.
• Simple & Bare-bones: It does not have built-in high-pass filters or pads, relying on its naturally flat frequency response.

Microphone Demos & Sound ProfilesBecause the NTK utilizes real tube circuitry, warming up the microphone for about 10 to 20 minutes before recording helps settle the high-end frequencies for a smoother tone.
