Let me begin with an apology to all the good people here that put up with me. I know I've posted a lot about this CMoy of mine but at this point I wouldn't be posting unless I had already worked on the thing for the past 6 hours to no avail.
It was working fine earlier today
I finally got my custom case (bottom) printed out today and I started temp mounting things in it with duct tape to see how theyd fit.
Everything fit ok and I was ready to test it again because some of the connections had been strained at times and I wanted to make sure everything was still ok.
Then it did the following.
It was showing signs of a bad connection to power or low battery- It would sound OK at first and then quickly (3-8 seconds in) degrade to a grindy distorted sound that was terrible. I started resoldering things (even replaced wire from V- to the DIP-8 V- pin) but to no avail...in fact, its gotten worse. I run my CMoy on 3 9v batteries currently and when measuring voltage off all three in series I got 25 Volts. I then measured their freshness (used a meter that had a built in function for it) and they were all near full. I switched out the oldest battery anyway but it didnt help. I have noticed that when i place my finger over the bottom of the right side of the DIP-8 Socket, specifically when my finger rests over V- and inverted input, the distortion goes away. its quieter than it should be but it goes away...or at least it did go away...now its gotten to the point that it takes /some/ of the distortion away doing that. Also when i pull my finger off it gets way louder for a moment and less distorted and then sinks back into its miserable state.
Pulling all the pieces out of the case did not help.
ANY IDEAS GREATLY APPRECIATED
EDIT: I have gone through tangent's headamp troubleshooting tutorial but my issue wasn't listed there so I just did some generic stuff (tested voltage at different places and connection between wires. I have not been able to Ohm out the socket yet as I really need to get to sleep but that will be the first thing I do tommorow.)
