I don't know of ANY amplifier that will work with a "Yeasu".
C'mon, you've never fat-fingered while typing?
'VSG - what kind of operating do you do, mostly? Amp selection depends on factors like:
- Do you need 160m? Not every amp covers Top Band.
- Do you operate CW, and need QSK?
- 120VAC or 220VAC to the shack? Not having 220 will limit your selections.
