FS: Threshold SA/3 Stasis Optical Bias Amp
The legendary Threshold SA/3 Stasis Optical Bias Class 'A' power amp by Nelson Pass. Most Threshold enthusiasts agree that the "SA/" models are the finest example of the Pass-era Threshold amps. It is most definitely "built like a tank"; no scratches or dents, and performs flawlessly. It includes a unique, high quality upgrade consisting of a close-coupled self-contained capacitor bank. Pause the music, drive the amp full bore and you won't hear a single sound...complete silence. Incredible soundstage from this high quality class 'A' power amplifier.
RATED OUTPUT: 50 watts/channel @.05% distortion
BANDWIDTH: -3dB at 7Hz and 100,000 Hz
SLEW RATE: greater than 50 volts per microsecond
INPUT IMPEDANCE: 75,000 ohms
OUTPUT TRANSISTOR COMPLEMENT: 14 transistors/channel
OUTPUT CURRENT CAPACITY: 16 continuous, 80 peak amperes (fuse governed)
POWER SUPPLY: 700 watt toroidal transformer, 60,000 microFarads capacitance
OUTPUT IMPEDANCE: Less than 0.03 Ohm 20Hz - 20,000 Hz
GAIN FACTOR: +26.6 dB
NOISE: No greater than -100dB, unweighted, referenced to rated output (input terminated in 600 ohms)
LOAD RATING: Operation is allowed into any load as permitted by power supply fuses and thermal protection.
WEIGHT: 56 lbs / 25.5 kg
DIMENSIONS: 9.6"H x 19"W x 13.125"D
