Hi all.
Finished up a caesar chorus build, I'm getting sound when bypassed, nothing when engaged. Led's both work, LFO pot adjusts flashing LED (seemingly) as it should. I've reflowed anything that looked suspect and most of the rest. Cleaned 2x with 99% Isopropyl, still nothing.
Gave it power and took IC readings:
IC1
1- 0.73-8.02 w LFO
2- 4.2-4.8
3- 2.6-6.3
4- 0
5- 4.1-4.5
6- 2.5
7- 2.4-6.5
8- 8.78
IC2
1- 5.08
2- 5.23
3- 4.96
4- 0
5- 5.03
6- 5.08
7- 5.08
8- 9.38
IC3
1- 0
2- 4.3
3- 4.96
4- 8.22
5- 8.79
6- 4.3
7- 5.87
8- 5.87
IC4
1- 8.78
2- 4.34
3- 0
4- 4.32
5- 0.18
6- 8.57
7- 2.8-3.15
8- 8.2
I saw someone else's thread w values posted and mine are off for some IC's. Still very much a newbie, so I'm at my technical knowledge limit at this point, but trying to learn as much about the how's and why's of my mistakes as well as better skills (my reflowing technique is largely reheating and adding a dab more solder -- may need improvement?)
Any help/advice/next steps is very much appreciated. Thanks!
