looks like C1 + connected to AGRND !
pucho812 said:I made one of these from the gerber files that are posted on the site recently I can't get it to work without problems.
I can run a sine wave into it at 1K but I do not get any real gain and the circuit has lots of noise...
I can't seem to figure out what the problem is... I followed the bom so I do not know where I am going wrong...
pucho812 said:I cut the trace, added the jumper and 10K resistor. Still no signal... Lots of noise though.... I will mess around with this some more and see what I can make happen, But let me know if you have a working unit...
pucho812 said:Front end is working fine... I send sine wave in. I redid the jumper across r20 and added the 10K resistor. Now I get sine wave on the output but the 1K pot does not do anything. I think I am going to restart from scratch and try again.... This is not to hard, I will get it right in the end.
