OPA2134 - source?

[lcipher3]

Getting quite a few projects on my list that specify OPA2134
Anyone have a reliable inexpensive source? Mouser and Digikey are $$$
There are some from China of course - but counterfeits abound.... anyone successfully buy from a seller?

(taydaelectronics doesn't have any in stock)

I would go with Digi-Key. But I would buy one 2134 and a batch of NE5532s. Socket them and see if there’s a difference...if there is then order up some more 2134s

I’m doing this experiment currently, as soon as my Delegate board arrives.

Good idea - nothing beats experimenting

If you don't mind adapters, the smd version of the opa2134 is cheaper. I have used the opa1642 as a replacement. It's a better chip. Not sure a guitar effect could do it justice. The opa1678 looks like a better chip, as well and it's less than a buck.

With effects sometimes the lesser quality is more better

Agreed. A lot times, delays, modulation pedals, compressors, boosts, buffers, mixers, adc, dacs, etc sound good with a good audio. Dirt pedals, depends on the design. Some dirt pedals sound like crap with a good opamp - Dist+, Crowther Hotcake, SS2 and many more. I wouldn't want a rat with an opa2134. However, the Vertex Ultraphonix sounds good with an opa2134. Or a zendrive with an ad712.

I've tried and tested quite a few chips including the opa2134 (american made) with a Zendrive, the Ultraphonix, and a few other pedals. I made recordings of all of them playing the same riff and chords; to my surprise, the obscure TLC2272CP chip sounded the best to my ears, and the ears of 3 friends of mine. It added some girth and clarity to the tone and a bit of sensitivity to the attack (dynamics). The opa2134 was a close second, follow by the AD712JN originally used in the Zendrive. I'm currently selling all the chips I tried in a bundle on Ebay including the TLC2272CP since I got 6 of them when I purchase them.

I bought mine from Smallbear.

I got a handful with my last Tayda order and they seem on par with any others I get. I suspect they're legit because the price is about on the same as everyone else if I recall.

I want to try the TL072 next...

I find the OPA2134 tends to get rid of the nasty fizz as the notes fade away so I would class it as Smooooth!!!
Very handy if a pedal has that flaw in it's design!

Did you ever try that tl072

Lotta counterfeit OPA2134s around. Get them from an authorized distributor like Mouser or DigiKey, otherwise you'll probably end up with a TL072 that's been scrubbed and relabeled. Not saying TL072 is bad, it's just not an OPA2134.
