The main power PCB fuse is fine and the unit switches on.
The voltage regulator small PCB also has a fuse but this is blowing. Despite changing the regulator transistors Q306 and Q307 and the main cap C324 the 0.2A fuse is still blowing.
Anyone know this unit well or knows what to look for next?

Resolved.
Desoldered pins 10 on both BA532 power amp IC's and the eq kicked in indicating audio was now flowing again.
2 new ones ordered and a replacement cap tethering pins 10.
Yay me.
