for home automation systems

GM70 Integrated Amplifier OMA's ultimate amplifier is a Single Ended Triode (SET) design producing 15 watts. Weighing 225 pounds and built on three chassis, The Hollander provides the most powerful, detailed and natural presentation of music possible when used with OMA or other high efficiency loudspeakers. Each chassis is built by hand from solid Pennsylvania black walnut with handmade dovetail joinery, finished in tung oil, and topped with slate. Inside heavy water jet cut steel plates support the 16 transformers wound custom for this amplifier. All wiring is done point to point by hand in a manner equal to the finest vintage professional broadcast equipment. The tube circuit features 12B4 low mu triodes driving AL4 meshplates (triode wired) transformer coupled to the copper plate GM70 Russian military directly heated triode output tubes. The signal chassis is connected to the power supply chassis and the filament supply chassis by umbilicals with military connectors, the power supply being tube regulated. There is an electronic high voltage delay circuit and an electronic relay system for selecting inputs.
