I took a hit from a nearby lightning strike. It took out my TV, Receiver, Bluray player, AND the amplifiers on my Mini Strata speakers! The fuses seem fine, the I/O button lights up, but I get NO base. I have connected a backup receiver to the line input an I get nothing. The same hookup to a standalone sub produces base, so I know my backup receiver is working properly. Any idea if this is repairable? I assume parts are hard to come by. Anything simple I can check myself. I really love (loved) these speakers.
