I didn't have a schematic for it. I did the PCB layout directly off the circuit on the breadboard. I was sketching it out to scan and post when I found a missing trace on the board. It is in the gerber file, but never made it to the board.
Anyway, it works now, as well as it did on breadboard. I do see the 358 clipping the signal at around 3 volts. I will order some MC34072 and a good selection of resistors and caps and see if I can improve it with some further research.
What value and type should I use for C4, the DC blocking cap between the op-amp and 567? Is there a formula for this based on freq? The datasheet shows it on every example, but offers no help on selecting it.
Thanks again for all your help. I am satisfied with the performance for now, it should only get better with the faster op-amp. Once I have this project done and I get more time, I will revisit this so I can actually understand all this better.
For now it is back to the land of 1's and 0's where everything is so much simpler.
Again, thanks.
