I am trying to understand your work, but i have noticed that the 1 you built (on the picture) does not have the 22uF 50v capacitor, this capacitor is shown on all the drawings you have posted, i am a bit confused because i have wired everything exactly as per drawing including the zener diodes which i have even tried changing in case i got it wrong, im going to try and take some photo's of my work to show u, i definately have no shorts as its very clear, bt its not really a work of art like yours lol, i really need to get this up and running because people around me are not well and also for other reasons, please reply soon as you are my only hope in this right now as i am following your drawing, thanks.
