Threshold S/500 Amplifier

In great shape with upgraded RCA and Speaker posts, I'm to old and its to heavy for me to keep. 2 small scraches on top, can see in pic. The Nelson Pass designed Threshold S/500 was built from 1(contact info removed). The Threshold S/500 is a solid-state stereo power amplifier known for its high power output and STASIS technology. It delivers 250 watts per channel into 8 ohms, with a maximum current output of 22 amps. The amplifier features a pure Class A voltage amplifier stage coupled to a Class AB current mirror, offering a balance of power and sonic neutrality. Key Specifications: Output Power: 250 watts per channel into 8 ohms (both channels driven). Class of Operation: Class A/AB STASIS (STASIS = Static Stabilized Amplifier). Frequency Response: 7Hz to 100kHz (-3dB). Slew Rate: Greater than 50V per microsecond. Input Impedance: 75k ohms. Output Impedance: Less than 0.1 ohm (20Hz-20kHz). Signal to Noise Ratio: -100dB, unweighted. Dimensions: 19" W x 19" D x 9-1/2" H (approx. 48.3 x 48.3 x 24.1 cm). Weight: 92 lbs (approx. 41.7 kg). Output Transistors: 20 per channel. Power Supply: 1000W toroidal transformer with 120,000 µF capacitance. Output Current Capability: 12A continuous, 100A peak per channel. Distortion: Less than 0.1% THD. Gain: +26.6dB.
