A huge thank you to the community and Tangent. Tangent I recently ordered a PPA and Pimeta but wanted to get my feet wet with a Cmoy.
First step by step everything was good and the troubleshooting along the way was helpful. I ended up with very very low right channel volume. I used the huge orange caps so I had to deviate a little from the schematic and after reading through about 20 "My cmoy doesn't work" posts I went line by line and discovered my error...Right channel output Cap was one line up from where it should have been, so of course there was no sound. (However there was a very faint sound).
My next problem was removing the battery and hooking up the DC power somehow I wasn't paying attention and hooked the batt+ and batt- socket backwords. I thought all was lost, the LED no longer comes on. After a bit of troubleshooting and everything being perfect a glance at the pdf vs my board made that mistake obvious. So I fixed it and now have beautiful sound out of the cmoy.
I have to admit I was a little ticked that you weren't here holding my hand through the tutorial. I was a little frustrated that I had to sit and fill everything out in a spreadsheet as I was going through because you list 10 ways to do everything and have 5 parts for each item. Without it, I wouldn't have learned a damn thing. I had to go and figure it out, watch DMM videos, read circuit diagrams, and troubleshoot shorts, and complete noob screwups.
I'm going to make a another cmoy for my wife then attempt the Pimeta and PPA.
Forgive my ending in a question...What gauge wire? I read hookup wire and bought some for the opamp but its tiny (30gauge precut some brand name), and then used 26gauge for everything else. Now that I"m all done I saw someone post 20 gauge... Am I screwed without larger wire in the long run?
Thanks,
Avi
PS MisterX's diagram on the pot was helpful to reference against the tangent tutorials and all the folks that helped out on the cmoy threads, thank you, it helped me too.
