Hello, is the TL082 chip considered to be a drop in replacement for the LF353? I had both lf353 chips go bad on the RCA input board causing my power amp to go straight to protect mode. I had some opa2132 chips on hand and installed them the problem was solved and the amp actually sounds better than before. If, the TL082 chips are a better drop in choice I can get them from my local RS. or would I be better off ordering some 0.1uf X7R caps to put from all four power pins of the two TL082 chips, to ground? I plan on ordering some of the X7R caps along with some other components anyway. Thanks for all advice! 
Oh, I don't I think you have just answered my question I'll just add the x7r caps to the 2132s when I get them. Thanks!
If the IC's really are failing then you need to address that issue. Could there be a dry on a regulator spiking the IC's ? Is the problem perhaps input related... are you plugging inputs with stuff powered up. DVD's, TV's can have fearsome voltages on any floating "grounds" but with no current behind them. Anything like that could degrade or fail an IC as connections were made.
Just a thought.
Just a thought.
I loaned the amp out and it came back with a couple crawling critters inside of it which, was the cause of the short out.
Needless to say, I'll never loan anything like that out again.
