Hi, can anyone recommend a op amp from CPC | CPC - Over 100, 000 products from one of the worlds leading distributors of electronic and related products. for CMOY headphone amp ?
It’s my first project and I can get everything for it from CPC except the Burr-Brown OPA132/134 series op-amps which is in the tutorial ..
“If you’re a raw newbie, I recommend that you try one of the Burr-Brown OPA132/134 series op-amps”
What I have done is match up the specs from mouser with the ones at cpc and not failed except the op amp. I don’t want the one part from Mouser as its £10 for shipping I’d rather spend that on better partsm also I only live 6 miles from CPC and I could be putting it together this weekend.. like if CPC have an op-amp that is a better spec etc. but being a total noob I’m struggling to match one up.. could someone help please ?

Just going from memory, didn't the original version of that circuit use the OPA2134? I think your supplier stocks that part. One logical upgrade within T.I.'s product line would be the OPA2604. In terms of pure value (price/performance tradeoff) in an application like this it's hard to beat the NE5532. I suspect the National LM4562 would also perform nicely. If you want a part with an absolute rock-bottom price - just to plug into the circuit and make some noise, proving that you haven't done something stupid with the wiring - try a TL072.
That particular design is quite straightforward and component selection is not especially critical. At last count I think there were about a jillion blogs, tutorials, and discussion threads about it. If you seed a search engine with "cmoy opamp substitute" you will probably encounter many more suggestions.

Ive tried the 4562 in a headphone amp , while it sounded good It couldn"t drive a 32 ohm load without paralelling them .....
LOL sorry for a total noob like me that meant nothing.. but I intend to get this all down in a website to help total n0obs understand the speak 🙂
