Original wooden case including everything needed for a high-performance ½″ measurement microphone:

Capsule 4166 (serial no. 1201084) – ½″ diffuse-field, externally polarized (200 V). Measured sensitivity: 4.7 mV/Pa (–46.5 dB re 1 V/Pa), typical frequency response 10 Hz – 20 kHz ±2 dB, max SPL 146 dB. Original calibration chart affixed inside the lid.

Preamplifier 2619 – ultra-low noise (< 10 µV), 10 Hz – 100 kHz bandwidth, integrated ~3 m cable with 7-pin B&K male connector.

UA 0196 Flexible Extension – stainless steel ½″ gooseneck for adjusting the capsule orientation up to 90° without moving the preamp.

Two threaded adapters: UA 0036 (½″ to ¼″ reducer) and UA 0035 (½″ to 1″ enlarger), allowing use with waveguides, calibrators, or couplers of different sizes.

Sealing/dust cap and intact velvet inserts.

Tested on B&K 2804 conditioner: output level and noise match specifications, no drift observed. Cosmetic condition close to new: shiny stainless steel, pristine case and foam interior.

Perfect set for acoustic labs, HATS mannequin measurements, or high-frequency transient recordings.
