The 2000s (as the 3000) are notorious for battery leak damage.
I heard good things about Acill, who is on his forum as well.
the 2000 caps leak less likely than the defective SMD caps used in the 4000 and 1200, some also in the 3000.
PSU recap is a great idea, ask Acill if he does that too.
A quick question for the electronic engineers among this crowd:
Some germans seem to love replacing the electrolytic caps with ceramic ones, any problems with that ? Other than microfractures from bending/soldering ? I certainly wouldnt want tantalum caps, they make a mess when they are goners....
