making a dual opamp
« on: April 16, 2008, 05:02:21 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?

       -in -I        I- ?
      out -I_____I- v+/v-?

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:-
