DACT CT1 Stepped Attenuator Volume Control (Used) SOLD
DACT (Danish Audio ConnecT) Stepped Attenuator. You can only find it in the volume control of the high-end preamp or integrated amp. Need not further introduction.
I have an unit stereo volume control CT1-50K-2 taken out from my DIY tube preamp. It is still in very good condition (measured each step with multimeter) with the specification as below.
KEY ELECTRICAL CHARACTERISTICS
Total resistance accuracy (new): 0.1%
DC attenuation accuracy (new): ±0.05dB
DC matching accuracy (tracking) (2 wafers): ±0.05dB
Contact resistance (new): Max. 0.01Ohm
Contact capacitance (adjacent contacts): 1pF
Series inductance (10kOhm version, pin 1 to 3): Max. 0.2
Bandwidth (10kOhm version, A=-6dB, deltaA=-3dB): 50MHz
Noise voltage (10kOhm version, pin 1 to 3): 12.8nV/sqrt(Hz)
Total harmonic distortion (A=-6dB, f=1kHz): Max. 0.0001%
Condition: 8/10
Price: SOLD
