Default Lm3886 dual monos-what size resistors?

Hi everyone:

Well, this is embarassing. I was all ready to solder in the replacement resistors I'd mentioned in another thread (Rs, Rf, R3, and mute resistor), into my Chipamp.com LM3886 boards, when I discovered I bought the wrong replacements.
I bought 1/4W for R2, Rf and R3, but they're too big.

Can anyone tell me What wattage/physical size are the resistors in those locations by default. Yet another thing that is not in the Chipamp.com manual.

Thanks.

Okay, it appears that the original resistors were between 3.0 and 3.25mm long. I'm guessing from that size, and the cost of the kit, that they were 1/4 W.

I'm gonna replace them with 1/2 W units that are closer to 3.5mm wide.
