Unhappy Mosfets for A75

Good Afternoon!
Can anyone recommend 220 package substitutes for the IRF230/9231 in the A75?
Being a neophyte I'm not certain which if any of the substitutes in the original article are 220. I checked Digi-Key online and found that most of the recommended subs were no lonegr available.

Thanks,
Gardenmann

Just about any IRF part will work. IRF540 and 9540 seem to
be common enough - you could probably get away with
using 1/2 as many.

When setting up this project, be very careful and be aware of output DC fluctuations. The amp is pretty powerfull and able to destroy your speakers as it is DC coupled as a whole.

I do have a large collection of factoids about amplifiers.
I'm giving them away as fast as I can....
