Where are you guys getting your LM308s? Small Bear doesn't have them anymore... what is the world coming to? I don't trust eBay. Mammoth want 3$ a piece for them and I don't want to give them my money if I can help it.

It appears that Jameco has them, but they are $7 a piece.

Smallbear has the metal can version if you can fit that in your design.

I got some at a local Radio Shack for a reasonable price not to long ago.

They might have them online

I got a bunch of eBay metal can ones not too long ago.  Extra mojo  8) if they work  :o

If you can't find anything I could send a couple along (assuming I can find them).  Let me know.

I have a bunch, 8 pin DINs.  Lemme know if you can't find one reasonably priced.

I got my last couple (metal cans) from an old electronics store. They're NTE labeled, but all they did was scrub the production label off and print "NTE 938" on. $2.50 a pop.

So far:

Small Bear: Not stocked anymore; Can version is $5.50
Mammoth: $3
PedalPartsPlus: $4
Futurlec: $2.30 (Probably fake)
Mouser: Call for quote (No thanks Mouser, if you're not gonna list your price I'll just go elsewhere)
Jameco: $6.95

I'm looking for a LM308 in the UK to do this project - http://tagboardeffects.blogspot.co.uk/2015/10/giant-hogweed.html - does anyone know a supplier preferably in the UK?

There is a store here in Paris that has them. But it costs 4 Euros. I can pick you up one if you want. With shipping to the UK it would be about 6 or 7 Euros.

If not. http://www.diystompboxes.com/smfforum/index.php?topic=33493.0

Thanks for the offer :-) I might check out alternatives first. I wonder if a TL071 would work?

I think so. Check the pinouts. IIRC you should omit the 30pf compensation cap between pin 1 and 8.

thesmokingman

without looking at the schematic, I couldn't say if the pedal is making good use of the lm308 or not(rat-like behavior), I would say the OP07 is a compensation cap adjustment away from working like the lm308. the lm301 is mushy by comparison. lm741 should work so long as you omit the comp cap same for ne5534
