Is the oscillator transformer the little blue dude just to the left of the cap in the photo? that's going to take some careful surgery if it is.

Just unsolder, rewind and resolder
I tried this this morning and got a surprise I wasn't expecting. The Khz reading dropped to 18.5 from 32.5 when I unwound one loop of the blue wire and reconnected it. Thinking maybe I needed to unwind a loop of each color I did one of the red wire too. It dropped even further. What exactly did you do when you did yours to raise the khz? Which wire and how many loops? Did I do something wrong?
Also puzzled by the fact that the voltage goes down when you take a loop of the bigger toroidial, but the Khz is supposed to go up when you take loops off the smaller one. Seems counter intuitive.
My process is to...
1. Remove it form the board (solder wick works OK for this)
2. Cut the two primary leads at the terminals
3. Remove the bit of remaining wire soldered to each terminal
4. Resolder the windings after removing all but one turn on each side of the primary
Vinnie, I can photograph this process if you want. I'm home from work today, so I have time to do this if it would be helpful.

Yes please! I am having a hard time understanding the process, and I really want to try this so I give it a fair trial. Thanks!
The center winding does not have any wraps.
The outside windings are just one wrap, not sure if direction makes a difference but I would think so, keep each winding identical just in case...

Thanks, I will try that in the morning.

Thanks deaf, that will help a lot in the morning. I will let you know how it turns out.
