Default Pioneer VSX-523-K Amplifier - Identify resistors

Hi folks,
New audio equipment repair and I could use some help.
Picked up VSX-523-K Surround sound amplifer.

Upon power up for the first time (been sitting for a while) loud popping noise and smoke..

Disconnected, opened up and found many popped caps on the amplifier board.
Replaced all, replaced A992 BJT, and pre-amp transistor and power transistor. I found 0.47 Ohm resistors that are blown or have gone High impedance and I'd like to replace.

On the service manual, it shows these as 0R47(2) (assuming this is a 0.47 Ohm, 2W?)

Question is .. what type of resistors are these? Flame proof, coated, .. ?? I see the leads have insulation of some kind. Just making sure I replace with appropriate resistors.

Thank you
