Av got audio compressor "hi-power model:cl-8000.for repair it uses tl074,jrc4580.but at the look of it some of the ic av been scratched previously by someone intensionally.so anyone with the full schematic diagram with the op-amp clearly labelled I would appreciate, generally they're 2(14pins) n 2(8pin) ic completely scratched off

My suspicion is it is a copy of a
dbx266. The giveaway would be if there are SIL ICs.

Anyone with schematic diagram of audio compressor hi-power model cl-8000 may share with me cz am working on it but it's ic chips labels are faced off by the former technician ab problems identifying the numbers

Main problem was that when I opened the inside for repairs I realized that the previous repairs was done n the IC chip around 4 of them were physically scratched n I cannot point out the numbers
