Most of the guys in Sacramento would drive their amps (old days 70's and 80's) with a 3 watt dead key....
Just because they did, doesn't mean you still should. It's an old tube amplifier. While it will probably work; it's best not to push it, unless you want to get good at replacing tubes & capacitors or worse, do damage to the radio...
If running at 3 watts gets you the full 50 watts out; running at 2 won't be that much different (40ish) that extra 10 watts isn't going to get you that much, and it will be easier on the amplifier & radio.
I tend to be more cautious when using amplifiers, push them too hard, they die and might take your radio with it. I would rather not get out as much and keep talking all day vs suddenly going off the air for a few days while I repair things.
I have midnight special & RM amps. They are all rated to accept 4 watts, but they caution you should use 1 to 2 to be easier. For that reason, I have modded my bearcat 980 to have a variable knob for power out - use an amplifier, dial it down to 1.5 ish; bear back, turn it back to 4ish. My other radios came with variable power ... Do I get the full rated power out? no, but they always work & I get out plenty when I need to.
Other than blowing up a 1K watt amplifier, the only time I've destroyed a radio or amplifier was when I was pushing 4 watts out. Once the same night I installed it; others at about a year or so of use. Caution goes a long way.
Another thing is most affordable (aka: cheap) amplifiers (tube or solid-state) do not handle 20 minutes of constant babble, they will overheat.
Oh, and yea... Amplifiers in the USA are illegal and shouldn't be used ;-)
Just my $.02, ymmv
