Yamaha XS-250: Stereo: 8ohm 170W, 4ohm 250W Bridge: ohm 500W Serviced by ATS Wellington, has moderate rack rash, internals are mint good condition for its age. Great vintage amp, rare as hens teeth, what it lacks in power and specs of today's standards it hold up in sound & quality good for mids or a single Sub. Originally purchased from a church 3 years ago so had an easy life. It has seen much action in my use and has toured a few times with no issues + serviced in my care. It was my starter amp when building my sound system, will be missed. Selling as I have upgraded and no longer have use for it, pick up available Palmerston North.
