making a dual opamp
« on: April 16, 2008, 09:02:21 PM »

in the old thread on this topic it said to simply make 2 and wire the v+ and v- together, but what about the rest of the leads?  where would they go in the socket. do they all just share the conections?

Lookup the pinout for the opamp you are going to replace.
You'll have an inverting and a non-inverting pin for each opamp, and an output for each.
For instance, there's a connection diagram for a TL082 opamp (which matches most dual opamps used in pedals ?) here:-
