Re: Creative Gigaworks S750

Hello everyone!
I am stumbled with gigaworks s750 SPS

Prehistory:
Several months ago I got this sub with blown fuse.
After unscrewing found just one visible damage, caused by spike at place of C62 and C7 just near the heat sink. Also observed bulged capacitors C59, C60, C69, C70 of different extent and a lot of darkened alien sperm covering most components.

Further examination revealed shorted diode D9 and overrated resistor R9 (measured 7 kOhm instead of 6.8 Ohm). These two were consequence of IC (TOP243Y)...
