Exc! Vintage Soundcraftsmen 630 Watt DJ900 Stereo Power Amp Amplifier USA made

This is in excellent condition. It is tested, and fully functional, with strong output on both channels. This is in super cosmetic shape. Not a beater. The fan is clean. Quality made in the USA. With 630 watts total output, this is one of Soundcraftsmen's most powerful amps. Strong enough to push a DJ setup,.. but with specs worthy of home stereo audiophile use. This was made before MTX bought out Soundcraftsmen. The pre MTX product is considered their best. If you know good amps, then you know what this is. A well preserved beauty from the golden age of Hifi. This model is a powerful, tough built amp. The DJ900 is the heavy duty version with 6 MOSFET output transistors per channel. It uses phase control regulation to regulate running voltage and self adjusts to temperature sensed at different spots on the heat-sink and transformer. It will run without shutting down even at the lowest impedance. It will keep up with the most demanding power hungry music for a long time.
