Using an ICOM 746 Pro with an AL-80B amp. According to their respective
manuals the AL-80B sources +12vdc at 100mA and the 746Pro can sink a max
of
+16vdc at 500mA.

QUESTION:
Do I need an amplifier keying buffer according to the above specs? My
research shows primarily these devices are for new rigs keying older amps.
The Icom site recommends an interface for "all non-Icom amplifiers" but in
the case of the above specs it appears to me there is already a 4 volt and
a
400mA "buffer" of sorts. The demands of the 80B are well inside the
capabilities of the 746 Pro. Right?

I'm not trying to save $50 or so but if the specs are right I don't need
it.
My rig is new and I have about 300 qsos so far which amount to at least
1000+ successful amp keying events.

You're an Extra and need to ask this? Come on, I've only (previously) held
a Tech Plus and know that 12V is less than 16V and 100ma is less than 500ma!
Man, when I go to take my elements I just may go straight to element 4 -
