Ok....bear with me - I'm an uber noob, but assure you that I have been extensively reading every possible FAQ and beginner question page prior to posting this.
This was my first ever circuit, breadboard, perf, solder job, enclosure, etc. Lots of firsts here. I'm figuring all of this out as I go along.
I troubleshooted the issues on my previous post - I had the wiring all screwy, all funky issues have been solved. Swapping out my mono input with a stereo TRS fixed the squealies.
I used a Radio Shack printed circuit board with the isolated horizontal copper rails on the back, so when I soldered I could keep it as close to my breadboard layout as possible.
I have 3 questions:
1. Do I need to connect pins 1 and 8 on the IC? My completed build sounds great, but taking a closer look at the Vero and Perf diagrams, they look connected. I definitely don't have them connected on my circuit.
2. I'm trying my hardest to wrap my brain around the layout of the 2 clipping diodes and how signal passes through them. Is this "symmetrical clipping"? Why are the diodes going in different directions?
In trying to get the bottom of it, I found this - is this my answer?"A diode clipping circuit can be used to limit the voltage swing of a signal. Figure [below] shows a diode circuit that clips both the positive and negative voltage swings to references voltages."
3. I used a non-polarized 2.2uf Cap, as this was the only 2.2uf Cap that Radio Shack happened to have in stock. Assume this is ok?
Thanks guys - pics below - VJ
(note, the back of the board does have the two diodes crossing the middle of the board)
