KRK Rokit 5 G3 Schematic Request

[BruceA]

Guys, if anyone has schematics for this speaker it would be a great help. I have seen the G2 model schematics but they made major changes.

I have repaired a number of those junkers.
Sadly, I never came across a schematic either.

Were you able to figure out the actual part number of the op amps? It looks like a quad package and they are made by ST but I think the number was made for KRK...I am waiting to see if ST replies. At this point I believe I had a bad cap as the +12V supply is loaded ...could be an op amp as well. Any common failure modes you have seen might help...thx

What is the number on the op amps themselves?

[Jazz P Bass]

My notes indicate the op amps are NJM4580

actually I was able to figure it out...the op amps are TL074cdts. These are for the G3 model.

I have the same model Rokit 5 3rd gen ,
got them from a friend both just stoped working the same time .
I replaced the 2 10 oem resistors by the led light indicator and the 2 35v 2200uf caps but no luck .
I shorted the pin for standby mode no audio from RCA , when I touch the leads of the TDA's (7294) I hear some feedback.
All fuses test good , no bulging caps .
Any idea what it could be ?
I asked the previous owner, he said he used it with an interface and it was still recognizing the speakers but was not outputting any audio.
