These sound as good as the original TI RC4558P op-amps I had
I didn't check every chip, since there are 100 of them. I replaced the 4 op-amps in a "Peavey Special 130" guitar amplifier because the old ones had corrosion on the pins. These replacements sound as good as the original 1982 Texas Instruments "RC4558P" op-amps that Peavey put in this amplifier. I am well pleased!
