Need a schem for this powered sub or one close if possible
Output power amp was extremely hot as it had some nasty high freq signal on it, then it blew.
Replaced output drivers and whatever else blown I could find, amp is now stable but has distorted output and signal overload at about 1/4 of the volume.
Preamp looks okay, injected a signal straight to power amp, and that's where it's distorting, one of the pre-driver stages.
Thanks all.
