I have made a new drawing of the solder paths, next i will make a components drawing based on the solder paths drawing.

Tedious job!

Hi All!


I have made a new drawing of the solder paths, next i will make a components drawing based on the solder paths drawing.

I have also added the 2 differences in what he changed before and after.

If i missed anything let me know, the dotted lines is what he removed.

Excellent work John!

I opened her up and at the CH2 entry the components are so small I am really not inclined to even try to poke around. I thought that maybe by fluke chance I could have seen a workable cap showing some evidence of blow up or overheating but these components are way to small. So I will use the CH A on this scope and then use my other scope, a Hitachi V650F. Not as advanced but this workhorse had served me well for many years with simple no frills waveform. Damn it, just when I wanted to do a video of my AK30, those frill would have come in handy.

@JohnnBlade

It's good to know that there are others here that have this stubborn streak when you decide to do something, you go all the way. Can't wait to learn what the cap values are for Pin 5. That damn pin 5 has had different values in every build schematic Akula put out. AK30 is at 3n, anther at 10n, I think another at 2.2n shown on the schematic. But this is supposed to provide the frequency range so why not just put what I have always thought should be there, a 1n cap.

i think its better to add a 12 step switch on the spot ( pin 5) where the cap is so you can easily change the cap values and have different ranges that you can test. i did that with my 555 timer circuit that i have been using for a while now. cause it would be a waste to desolder the cap everytime when you wanna try a different range.
