Vintage amplifier specifications

I've noticed when I read vintage amplifier specifications, and by vintage I mean 70's,80's maybe 90's, I do not see power output specified at 4 ohms. Did those older amplifiers not do well on 4 ohm speakers so leave that information out or was it not considered a a matter of interest to the buying public. Maybe something else?

I should add that a lot of those old amplifiers, usually integrated had hookups for two sets of speakers which could really drop the total impedance. Maybe a lot of those old units had short lives or they could handle it without issue?

So two pair of speakers weren't necessarily amp killers in the days of yore so perhaps those old amps were more tolerant with beefier construction than I suspected.

Now days the low impedance load handled by amplifiers are selling points or bragging rights for manufacturers. Who doesn't love an amp that can "double-down"?
