Sorry, I do not understand your post. Are you saying the dealer (Repair Shop) attempted to fix your Levinson amplifier and "during" the repair process, they destroyed your Levinson (they blew it up)? If this is the case, the dealer owes you a replacement amplifier. This means, I think, they owe you for the current estimated value of your Levinson amplifier. In other words, they should offer you a credit on your broken amplifier for a new or used one in their store. What was the condition of the Levinson amplifier when you delivered it to the repair shop? Please let us know what happens.
