I am in the process of repairing an AWE64 Value CT4520. It had several damaged or ripped electrolytics on the PCB which I replaced, at which point the ISA bus started seeing the card and initializing it. It works with UNISOUND (which strangely reports only 64KB of AWE RAM, but maybe that is normal) but I only get proper sound out of Line Out. From SPK Out I get (as far as I can tell) nothing from the left channel and a very muffled and very low sound from the right channel. The two Nichikon 470uF 16V caps right after TDA1517P amplifier were somewhat damaged but I left them as I did not have high quality electrolytics to replace them with. Now I think they were probably damaged enough to leak and dry out. Also, the back of the board has discolored towards a brown under these capacitors, as well as the 100uF 16V ones on the other side of the amplifier. Maybe all four are leaking and need to be replaced?
