Here is a project 2x4 erf 7530 mosfet amp. I bought it this way but am not a amp person. I run my stryker 440 thru it at 8 watt DK amp keys 30 swings around 150. This thing needs a higher drive to get it going like the 7530 amps. Asking $70 plus actual shipping cost. Has more than that in mosfets. Also open to a trade?
