Very good condition QSC PLX-1804 power amp for sale. $450 shipped in the contiguous US including insurance. Must ship to physical address (no APO/FPO/PO boxes). Local to Des Moines, IA: $400. Works great, I'm just not using it anymore. I also have an Ampeg SVP-II pre-amp for sale. Specs: Only 13 pounds 2-rack space 9" deep 550 watts RMS per channel @ 8-ohms 800 watts RMS per channel @ 4-ohms Best thing about this is the SHALLOW depth and crazy light weight! This amp fits in many lighter/smaller racks where the full-size PLX-##02 amps will not. Paypal accepted, but it must ship to your verified/confirmed address. USPS Postal Money Orders accepted, as well.
