Vintage Audiophile Dynaco/Dynakit ST-150 Stereo Power Amplifier Rare Kit Built. Used as is

Item has faulty power switch. It will power on, occasionally, but needs a switch. Because of age and no use since 1980 should be serviced before use. Item was working before storage in 1980. Case is very clean. Will be a killer stereo amp after service. Includes original manual and schematic. See photos for details
