Peavey Classic 20 guitar amp...

R32, lower right corner of the schematic,
tucked under VR1, lower right corner of PC board.

Component is a fixed resistor with a value of "47FP".
What is that?

Also, the two ends of the resistor
go to ground. One ground symbol is
the traditional inverted triangle,
the other is the same triangle contained
within a circle.
What is that?
