Good replacment for TL081C

odysseyvn · 1st May 2005, 07:08 PM

My power amp use two TL081C. I want to improve it. Can I use BB opa 134 or BB opa 637 replace it.
Thank for all advice

Yes

If you replace tl081 with opa637,the tl081 should have a gain of at less 5. OPA637 is unstable with less than 5

TLO71 should be a good head start
