I have not seen one of the these amplifiers posted on here so I figured I would post some photos and hopefully get a question or two answered.
This amp uses P65NF06's in the power section and 10ohm Gate resistors.
Can I use IRF3205's as subs?
The audio section uses FQP19N20C with 10ohm gate resistors in the audio section.
Can I use IRF640's or IRF640N? I have both.
I have a batch of MM74HC02M from a JL1000/1 I had worked on. Would this work? I am unsure which one to order I have attached a photo for comparison. I am unsure of the difference between the 3.

The 3205s will work. If the drivers are weak, either use better drivers or go to 47 ohm gate resistors.
What's the reason that you don't think the JL parts will work?
The 640N may work. If not, try the IRFB31N20D.

The part numbers are similar but different and the comparison tool on Mouser is showing different specs. I am referencing the photo attached.
No. of input lines and No. of output lines. 74HC02D, 662 is showing 4 output and 8 input. I assume it is different than the other 2 I am not sure.
The one I have is a MM74HC02M.
I dont have any experience with this IC and the last batch I ordered I copied from the part number taken from your JL 1000/1 page.
I have minimal experience dealing with logic level stuff. Most of my experience has been with the Generic Class D Type 3, Type 7, and 8 as that is what I encounter most.

Look up the original datasheets. Do they have the same differences on the manufacturers original datasheets?
I apologize for wasting your time i should have checked the datasheet. The only differences i can find is the manufacturer, The ON Semiconductor max operating temperature is lower (85° vs 125°) and different packaging tube vs cut tape.
