Will a concert lead comfortably push two 6/10 cabs?

Being a solid state would it still be important to match the load?
and what is the proper load to put on this head?
it has two speaker outs, so i aqssume its fine to run both cabs just wanna be safe.

Somewhere between 74 and 79 the Concert Lead went from 150W/4 ohm to 200W 2 ohm. 6x10s are typically 5.33 ohms so two of them would be 2.66 ohms. Not safe on the first generation which has no short circuit protection. You could rewire the cabinets to be 12 ohms so a pair would be 6 ohms.

heres my serial number 027658
does this tell the date? or the load requirments?
i'm kinda suprised its not labeled on the back (ohms)
what two speaker cabs with what values where intended to go in the two speaker outs on the back?

also my 610s has two jacks on back.
i assume its in and out, for mono connection of two cabs?
would this setup work for my concert lead?
or is that just another input for some odd reason?
and my 610s cab is 5ohm load and the other acoustic 104 6 10 cab is around 4, measured with a multi meter in resistance/ohms.
with a short gold conductor monster cable.
