Title: Stage Center Reverb Circuit build Question[s]
Post by: petemoore on June 14, 2004, 07:53:41 PM
What do the letters and numbers mean, or what are they there for?
 A,B,C,D,E,F,G, I AND X: LETTERS
 +9 and -9...
 Wouldn't the +9 go to pins 8 [I'd be using two dual OA's]
 Is there no need for 1/2 voltage biasing with the +9 and -9 power supply?

I'd guess those letters and numbers are solderpoints for of board wiring.

Those letters are points where the circuit leaves the board and you need to attach a wire. Dmn I hate ofboard wiring :x

I presume you're using a PCB layout for modern opamps.  If you're using the layout for a 4136 you're SOL.

Looks like two dual's [opamps] would do the trick.

... unless you've read the articles at GEO - like "http://geofex.com/FX_images/anderton.gif" for how to mount any IC on any PCB pinout using the "dead bug" technique.
