KRK Classic 5 G3

Good day to everybody....hope all is getting through these rough times.....IS it possible that somebody here on the forum would have a schematic for this one....it would make the trouble shooting job a tad easier....

I tried to get one but apparently there is none in existence.
It is a very simple amplifier that uses a chip amp and depending on model either a class D sub amp or a TDA chip.
What happens is the black gunge they use to stop the components from falling off the board or vibrating, gets porous, absorbs moisture and stops the sub first and then the tweeter amps from working.
Clean it all off and replace the corroded components, sweaty smoothing capacitors and it should work again.

It uses TDA chips for both drivers...doesn't look like there is any of that black glue on there...strange.....anyway I will check it out after the weekend...I did search for schematics for it but there are none to be found.....will have to do it without them...
