I would love to find some one within driving distance (75-100 miles) of greater Cincinnati, but willing to ship if necessary and with a good reputation. Really can't afford a new amp and would like to have this one repaired. Signal is "horribly" distorted when using the amp. Kind of happened out of no-where. Worked great for about 5 years. Wish I had the talent to diagnose, but sadly I don't. Any suggestions would be greatly appreciated!
