Title: MOOD RING - Couple of Issues
Post by: trailer on March 28, 2018, 11:03:15 AM
Got it all together and I believe all my components are correct but I'm having some issues...

When toggled, on one switch setting there is a huge amount of gain or distortion coming through. I tried adjusting the volume and gain trimmers and they are barely even on with the same problem. On the other switch setting the volume is much quiter and it sounds like I'm playing through an old radio with dying batteries, and there is about a one second delay on my attack.

My voltages are:

IC1
1: 4.55 
2: 4.55
3: 4.55
4: 0
5: 4.55
6: 4.55
7: 4.55
8: 9.13

IC2
1: 5.06
2: .5 mv
3: -
4: 0
5: .1 - 1 mv
6: 2-3.1 mv

IC3
1: 4.98
2: 2.48
3: 0
4: 0
5: 2.78
6: 2.47
7: 1.46 - 1.51
8: 1.5 - 1.69
9: 2.48
10: 2.48
11: 2.48
12: 2.48
13: 2.48
14: 2.48
15: 2.48
16: 2.48

IC4
1: 4.56
2: 4.56
3: 4.13
4: 0
5: 4.13
6: 4.54
7: 4.54
8: 9.13

Q1:
D: 9.13
S: .57
G: .4mv (was erratic but settled here)

I swear this is my last build without a testing rig. Way to much of a headache without one.
