Question what are the aleph 1.2 resistor wattage values?

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

As far as I know Pass Labs is using 3W Panasonic resistors from Digi-Key.

I think Peter is right and it seems the Pansonics are common in the Pass products.

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:

The type used I think for the 1.5 and 0.47 would be:

P1.5W-3BK-ND
P0.47W-3BK-ND

In a similar vein:

Does anyone know which brand of resistors are used in the original Alephs?

Cheers
