no it dose't i have had plennty of amps do this and it's never hert them yet or offected the output eatherRadioshack sucks for electronic componants. I guarentee they won't have it. Also, DO NOT run the amp short of a mosfet. It'll change the way the electronics work and could cause a total failure.
Mosfets usually have a part number printed on them. Do NOT do what maxxguy1 said about pulling out the mosfet and the wires.
