dummy load

need a dummy load for test amps... easy 4 high power 8 ohm /50 watt resistors wired in series parallel. and hooked up to an input jack. thats a 2oowatt resistive load. now you can run your freshly built head at full last without damaging your amp or your ears, i'd tell you step by step but its so simple i dont think i need to explain. but i will say this. an aluminum housing is recomended for heat dissapation cause these things do get hot. but sticking with the salvage theme of the tools i used i ended up going with an old drill bit case. the parts are easy to find through mouser dale/vishay high power resistors 80hm/50watt and this is alot cheaper than buying a dummy load.
heres the pics.
