KRK tweeter squeal

Hi all

I have a Rokit that has a LOUD tweeter oscillation So loud, one has to shut the amp down immediately for fear of the driver blowing.

I have recapped the main caps and cleaned the Gob off with Acetone, but I am still getting a 3.4 volt DC offset from the HF amp. I also replaced the 2k2 resistor that had blown.

My next step is to get the PCB washed in an Ultrasonic bath, but it is a quite a hassle to get this done.

Any ideas? Anyone have the KRK schems from the old forum, the links are dead

Many thanks
Peter
