There is a 10uf electrolytic (301/401) in the signalpath, and a few ceramic caps that could be replaced to Wima FKP for example. I would recommed to replace all caps. My 2200uf/ 50V was leaking.
Like sgrossklass said they're totally let doen by bad parts and mostly here its the caps.. JH (jinghai?) and the are BAD.

Also replace the 4x2.2K (3W) res to 5w, they run insanely hot! Also down by the 18v reg there is 2x200R that could be 3w instead of 1W.

Have you checked all voltages? 18, 64 and 68 if i remember right

Anyway this amp was manufactured from 2003 to 2008. The C275 came after that.

Btw, i think this amps sounds far from sharp, with my Be tweeters it is very sweet and warm treble.
