Super Sonic 02 IC questions

[Anonymous]

Hi guys (gals)?

Just got my Supersonic 2 board in the mail (thanks for the super handy cap/resistor chart, Barry).  I was looking through my ever-growing parts stash before I start building and I have everything except the ICs specified in the build doc.  I have on hand 4558s, TL072s, and OPA 2134s.  Would those work (and work well) or do I need to order some ICs?  I have recently moved on from kits (have built around 25 or so) and am new at sourcing my own components, so just want to make sure I have a working pedal when finished.  I like using the OPA2134s whenever possible because my dad was an engineer at Burr Brown  and helped develop those chips, so he always likes to hear about me using them (even though he hated when TI bought them out and retired shortly after).  Anyways, thanks for any advice you might have.

Hi Jon

You’ll need to order some op amps

The ones you have are dual op amps you need single op amps an LM741 and TL071

Just for info op amps come in single, dual and quad packages meaning they either have 1, 2 or 4 op amp circuits internally in the same package and therefore the pin outs are different

The TL series are easy to tell the difference

TL071 with the 1 denoting 1 internal circuit (single) 8 pin package or DIP 8, DIP = dual inline package meaning the pins are on both sides, the 8 denoting the number of pins in this case 8 dual inline so 4 per side

TL072  with 2 denoting 2 internal circuits (dual) 8 pin package or DIP 8

and obviously the  TL074 with 4 denoting 4 internal circuits (quad) 14 pin package or DIP 14

Unfortunately not all manufacturers make it easy to know which package it is, but most suppliers do state whether it’s single or dual

The confusion arises because the same physical package is used with single and dual op amps ie they both have 8 pins

There is a little information on op amps in the beginners guide to effects pedal components on the guides page

If you look at the pinout diagrams for the TL071 and TL072 on Google you’ll see the different pin allocations etc

Thanks for the helpful info, Billy,

I have scanned and stored for future reference.  MANY THANKS!

Wilkie1 – I cleaned up the Apple textural artifacts. (I should’ve double-checked after posting.)

Thanks Cybercow.  That is immensely helpful.  I have checked out some of your builds, and I must say they are inspiring.  I will no doubt be here for some troubleshooting.
