Sourcing LM308s?

[WheatAndBarley]

Anyone got line on some legit LM308s right now? Currently waiting for more parts for my parentheses mini so I thought I might as well try to get an actual LM308 in the meantime.

I think fuzz dog may have some but they are only available if you buy their rat kit.

Let's say it's hard these days to get legit LM308s. For the Parentheses Mini, especially with the octave on I feel like it doesn't matter that much. Either go OP07 or LM301, or leave out the compensation cap and use an LM/uA741 of sorts.

@fig customer on isle 3 needs assistance. Thank you for shopping at Fig-Mart for all your pedal needs. Someone will be with you shortly.

I have yet to encounter a component @fig does NOT have.

When I switched out my non Lm308 chip out of my parentheses mini with a legit LM308 it was like a beam of light broke through my ceiling and there were magic harmonics screaming out of my amp. It might be in my head but I can hear a difference. The octave part aside though, as jesuscrisp is correct.

Apparently, the only ones I don't have are ones that I need for a build.
I do have an extra.

DM me if you want that mojo in a box feeling.

Edit: Just checked....about a dozen extras

Like @fig I stocked up when they began to get scarce! Hell, I've stocked up on stuff I've never used and may not ever, but by God I got it!

How many Rats can one man build? before they call him a rodent!

I'll take a look - I do have OP07's

I actually only have 2...one is a breadboard. I seem to recall a group buy on 308s...then I scored the NOS 83s. It just kinda happens.

What is the real-world difference between a LM308 and the available OP07?

Absolutely nothing.

I believe one of the key characteristics of the op amp selection is the slew rate. Both the OP07 and the LM308 have a designed slew rate of 0.3V/µs, whereas a TL071 is 13V/µs.

Component mojo always gets lost in the mix. Finger mojo on the other hand..

I'll submit that component mojo can trigger endorphinal creativity and confidence, therefore actually improving one's musical capability. Once those peppy little peptides stroke your opiate receptors, you're off to see the Wizard my friend.
So yes Virginia, mojo IS real world.

So this mojo means we are absolutely not in Kansas anymore? Or Boston?

Sometimes I forget that not only are some of my references obscure and/or regional in nature...they're outright OLD.

Sep 21 1897. In answer to an eight-year old's question to The Sun Editor; "Tell me the truth. Is there really a Santa Claus?"

Apropos considering the topic?

The Wizard of Oz isn’t old, just me, I fear.

But in any case us wayward sons will carry on regardless in search of more than a feeling. ‘Peppy little peptides‘ is up to the minute, microbiologically speaking. Excuse me, I hear the faint call of my soldering iron. Must dash.

Honestly, there really is something to be said for that. Music is subjective, and how you feel about a piece of gear often matters more than “does it sound better than X.”

Your Kemper patch probably sounds better than my amp, but dammit my amp just makes me happy in a way a modeler never will.

I use OP07 for SMD Rat builds and LM308AH (metal can) in through-hole builds. OP07 is easy to source, LM308AH I generally get from eBay. If you're seeing them in China for $1-2 a piece they're going to be fake, if the seller is in Europe and asking around $10 a piece they're more likely legit.
