Lawrence,
Thanks for the video link. Well worth watching to anyone who thought that working out this is tough. I have made notes and run through some examples on my own scope and gone over and over it till its sunk in and I can do it without really thinking about it. Getting the right amount of decimal places so you got the correct frequency at the end. Your example, Lawrence combined with the video has made things very clear. All part my learning curve.

So, after this I tackled the problem of LW on this set being wildly out of tune due to not enough capacitance across C33. I used my scope and the math I learned, and guess what?
