I am not sure if i am calculating the wattage values for the resistors on an aleph 1.2 output mosfets drain and source. R64-75 and R40-51 at 1.5 ohms on the source of each output are 2 watt resistors, right?????? R22-27 and R100 0.47 are 1 watt resistors on the drain of each output

I was however a little concerned about the phrasing in your question: "R22-27 and R100 0.47 are 1 watt resistors on the drain of each output" This set of 7 resistors is common for the whole output section and should not be duplicated for each lower output FET drain. The Panasonics are at: http://info.digikey.com/T023/V5/0672.pdf The type used I think for the 1.5 and 0.47 would be: P1.5W-3BK-ND P0.47W-3BK-ND /UrSv
