JL Audio 4.300 output section question

I have a JL Audio 300 watt 4 channel amp in my shop with one channel shorted. The other three channels all test good.

I notice that two of the channels have dual IRF540 mosfets and the other two have one IRF540 and one NTE 2396.

The one channel that is shorted has an NTE mosfet paired with a IRF540.
Both of them tested shorted like resistors.

I was wondering if I needed to go back with an NTE (I’d have to order some at about 6 dollars a piece plus shipping) or if there was a cheaper, viable substitute for it. All of the output transistors are utilizing 100 ohm gate resistors.
