Do the MOSFETs require matching for the Aleph J?

Yes.

However, you only need match the Mosfets that share current - Meaning you may use a pair that has the same Vgs for the Current source fets (Q5, Q6) and a pair that has a different Vgs for the power output (Q7, Q8).

Yes, a matched Quad per channel, or a matched Octet for a stereo amp is more convenient, it isn't necessary.

OK thanks. I'm assuming the same goes for F4 too?

Yes, the N must match the N, and the P match the P, but no need to match N to the P.

Bummer. If you can let me know where you're able to source them, I would appreciate it

Can you help me with what input I should ground for RCA? Is it IN- that goes to ground and IN+ is an actual input? Thank you!
