I got both channels working, but I can only adjust the freq. at D1 cathode down to 320khz for both channels, it seems to be compressing ok, Looks like the waveform is correct at D1also.
Has anyone had this issue of not getting the freq. to 250khz?

I forgot to mention when I finished the first channel I was able to dial in 250khz, but after completing the second channel I went back to the first channel to make sure it was still at 250khz and it changed to a much higher level,, very weird, and the second channel the same.
Can anyone help me to figure out why this jumped to a higher level?

I don't know why I keep posting on this group, don't think anyone cares LOL
anyway I changed the trimmer pot on the Monolithic board to 25k and now I can dial in the 250khz. The compression seems to be working better with the correct freq set.

I definitely care! But I know I'm just one random dude who isn't even working on the project currently... Glad you got it dialed in!

Lots of people read and rarely if ever post. Please keep posting.
Hi Jen
I am busy with other things, but I will post once this compressor is in my rack, It's hard to tell if this is compressing properly, it's not like any other compressors I built, very transparent, It's unfortunate the person that created this project is gone, seems like he is very talented, and probability could have answered a lot of questions people had on this build.

I'm interested and following this thread. Had mine working, had an issue with the meters not going to zero and then shorted something while poking around. I will get this project out in the near future. From memory I had issues with the oscillator chip not dialling in but wasn't sure if this was my scope setup or the build issue. I do not recall a full and precise setup available on this thread when doing a full trawl. If people start posting there setup procedures we might be able to get a definitive guide for this.

I tried the short setup Abe had in his notes, I was able to dial in unity for input/output, and setting the oscillator is straight forward, but the other procedures of setup didn't work as he described, or I am not following correctly.
