Tested and working classic US made solid state mono block amplifier.
Working 100%. Good sound quality with no hum or distortion. Volume control, power switch, and power light are all working correctly. Some minor cosmetic wear to the paint on the front, not bad. Rack mountable. Hooked up a CD player directly to input to test, sounded very good. YouTube video taken to demonstrate the working condition will share on request.
Back in the day these were the "standard" for many venues including halls, clubs, movie theaters, etc. Built like a tank and versatile could handle speaker loads for 4 ohm to 50 ohm. Optional plug in modules are available for use with microphones and other accessories.
