Matched mosfets from the store

Hey all

I bought the mosfet pack for the aleph j.

i was just wondering it it would be worth while for me to go through and check all the values on them? or should all 8 already be matched? (i was unsure if they just match each channel or all 8)

Thanks in advance
 
I am the one that puts the mosfets together for the kits.
If they have values written on the backsides then they have already been tested.
I test the mosfets at 24V 200mA with a 30second warm up prior to recording the value.
Feel free to PM me if you have any more specific questions.
