I see in older threads that some say beware of Jameco, while I know others of you have no problem shopping there. So has anyone actually tried one of these to see if they're legit?
Everything I’ve read (I don’t have an original 308 to do a side by side) says the op07 is just fine and it’s like the old tube screamers with the chip.

I bought an LM308 from Jameco a couple years ago. It has the exact same numbers as an LM308 I got on Ebay a couple years before that--and also a couple photos when I google "LM308" show those numbers. That's suspicious
Both work in a rat circuit and sound OK, like OP07 OK. I'd have to sciences it in order to really distinguish a difference. I put it in a DOD250 (adding the cap) and I really like it.
That said, I doubt it's genuine and it certainly doesn't scratch the "I've got a real LM308" itch. Which, in this hobby, is a valid and legit sentiment.
I have one legit LM308 that I have a/b’d against OP07 in my rats and rat-alikes. It’s fun to have a 308 in the pedal, but really truly the OP07 sounds exactly the same. I enjoy grabbing nos parts when I can, so I can sympathize. But yeah who knows what those ics actually are.
I bought 2 lm308s from Jameco about 6 months ago. They are real and arrived fairly quickly. I’ve got one in a PPCB parentheses mini and the other is going to go in sushi box lab rat.

I bought their LM308n for my recent Parenthesis Fuzz build. It sounded great! Truly no idea how authentic or NOS or any of that it is. But I will say it sounded great at least! (see recent post history for demo)
this popped up in another thread. i wish i had bought these instead haha. i think i paid too much for shipping from jameco but they were the only ones i could find at the time
I bought one of these just now. I've got some op07 on hand and a few other workalikes. I'm gonna go down the rabbit hole and check them all out when this LM308H arrives.
I've procured a few of the Jameco LM308N single opamps and they are indeed genuine. At least, they work in my Rat builds and sound the same when swapping between them and an OP07.
If you have one of those cheap Chinese GM-328 testers, you can use this diagram to verify a genuine 308 . . . .
And for the sake of simple pin-for-pin equivalents, here's a list of opamps that are swappable in their respective pin-outs . . . .
Thanks for all the feedback everyone. I agree that there is no way they are NOS. Maybe some Chinese manufacturer is trying reproduce them to similar specs as the ones of old? Highly questionable either way, and the fact it was mentioned above that Jameco has sold other fake stuff is enough for me to stay away.
Buuut...just this once I'm going to buy one just to see what they sound like. I can't help myself...just have to know. Yes, I'm bonkers, I know, but at least I know what I'm getting into
