Description
Hot House S400 Stereo Hi-Current MOSFET Control Room Amplifier Estimated Year: Early–Mid 1990s Made in: USA Used Hot House S400 Stereo MOSFET Amplifier Overview The Hot House S400 is a stereo hi-current MOSFET control room amplifier designed for studio monitoring and high-fidelity applications. Built in the USA, this rackmount power amp features a minimalist front panel and substantial external heat sinks for efficient cooling and clean power delivery. Rated with 30dB gain and 51k ohm input impedance (non-inverting), the S400 is built to deliver stable, high-current output for nearfield or control room monitors. The rear panel includes 1/4" inputs and binding post speaker outputs for each channel. A solid vintage studio power amp with classic MOSFET warmth and punch—ideal for project studios, hi-fi setups, or rack-based monitoring systems. Features - Stereo hi-current MOSFET power amplifier - Control room / studio monitoring design - 30dB gain - 51k ohm input impedance - Non-inverting design - 1/4" inputs - Binding post speaker outputs (per channel) - 5 Amp Type 3AG fuse - 120V AC, 60Hz operation - Heavy-duty external heat sinks - Made in USA Condition Good condition. - Powers on and tested for output - Cosmetic wear and rack marks on faceplate - Heat sinks in good structural shape - Original attached power cord included Store Policies - All items are tested before listing and again before shipping. - Orders typically ship next business day. - Shipping is available to the continental U.S. only. - We do not accept trades on shipped items. - Returns are accepted within 48 hours of delivery.
