Re: J31Rob & robbyboy32 issue.
I wouldn't pay him a dime. He is responsible for verifying the amps working condition after shipment is received. 6 months is too long to extend a warranty or refund for a used product. If other information comes to light, it could change the situation. But if he just contacted you after 6 months about this problem, he probably damaged it during use and is trying to not lose money.
