I sold him a zed nakamichi pa502. I didn't bench it before I sent it out. Worked when removed. He got it and it will only power on for a second and then shuts back off. Refunded his money and I hope it is a simple fix. If anyone can fix it for him please give him a shout. He likes old zednaks so I hope he can get it to work out for him. Good buyer, honest guy. Someone help him out!
