I've looked at gate resistors for fets in similar amps, & the others
in s.e.r agree, this is probably a low value part, so the part number
would be 4XR5, making it 40 something ohms. The fets popped, which
caused these resistors to blow.

Since 5% (E24 series) parts don't have three significant digits in
their values and 4R5 isn't a valid 5% value, these should be 1% (E96
series) resistors if the legend is, in fact, 4XR5.

Furthermore, for any value starting with 4 and ending in 5, the only
possible value for X is 7.

If the legending isn't 4XR5, but 4X5, then it should be a 475 ohm 1%
resistor.

That is the only valid 5% schedule part to match it. Unless it is a
custom part, I'd say that that is the correct valuation.

---
Don't you mean 1% schedule part?

JF

Not with only three digits in the value expression.

---
Point is (unless it's a 4.7 megohm resistor) '475' can't describe a
valid E24 series part.

OTOH, since the middle digit's gone, it could be something like a
Panasonic ERJXXQX4R7X.
