Looks like Nelson decided 1.5A sounds better than 1.3A.

2.4R in parallel probertly gives te best balance in current and you might mix the gate resistor with the 150R used for current limiting...

"Do It Yourself" and share your job...
Here my (very modest) contribute to the cause.
The program is the well-known ExpressPCB.
The imagine (copper side) is reversed, so is perfect for "laser printer and iron" technique.

The 2.4 ohm resistor was used to trim for lowest distortion, which I
do if the channel exceeds .005% at 1 watt. As I have said, you need
an analyzer to be able to do this. A minority of channels need this,
and it is random in value and placement.

They would be sleeping, probably over the life of F5 operation...
Forget their stability, grab any one and use it...

Hi
Is the pair of 2sa970/2sc2240 will be a good replacement for ZTX450/ZTX550?
