  • KRK (Gibson) Rcokit 8 Schematic, componet identification help

    Looking for a schematic for a KRK (Owned by Gibson Corp) Rockit 8 powered speaker. Trying to identify the two IC's (Amplifiers?) on the Main/Power Supply PCB, and troubleshoot the same board. Came in with the 15 pin having a hole burned through it, right through the P/N. Appears to be a TDA7293, but not sure. The 7 pin is possibly a TDA 2052, which I suspect is bad) but the markings are also nearly illegible. Reading 3.5VDC on the tweeter Positive, which is tied to the 7pin IC #1 leg. Also reading 3.5VDC on leg 6 (Inverting input?) and neg rail voltage (-22VDC on Pin 3 (Standby?). Have previously got a Rockit 10 schematic (very dissimilar design) from Gibson, but that was like pulling teeth. Gibson Tech Support has now been ignoring me on this request since early last week, must have used up my quota of schematics (one this year) from them. Any and all assistance would be greatly appreciated.
    Thanks.
