Re: I've built my own single 9V dc beck's blood cleaner

have you measured output from your electrodes? is it 27v? if it is not it could be wrong size resistor.

check the polarity of CAP 22uF 50V, also check the direction of zenner diodes, and also make sure you are using .1 uF CAP from pin 2 to ground - if you have wrong CAP here it will increase or decrease the frequency of output. I mistakenly put a smaller CAP I had available from building Hulda Clark Zapper which is .01 uF (LOL only 1 zero difference but my frequency was 3,500 Hz) so the led appeared to be constantly on.
next thing to check if you are using the correct resistor sizes in correct locations.

here is quick resistor color code:

1st and 2 color - 3rd color
Black = 0 - black x 1 or 0 x 1 = 0
Brown = 1 - Brown x 10 1 x 10 = 10
Red = 2 - Red x 100
Orange = 3 - Orange x 1k
Yellow = 4 - Yellow x 10k
Green = 5 - Green x 100k
Blue = 6 - Blue x 1Meg
Violet = 7 - Silver divide by 100
Gray = 8 - Gold divide by 10
White = 9

Fourth color band = tolerance
Gold = 5%, Silver = 10%, none = 20%

Example:
100K = Brown, Black, Yellow, Gold
150K = Brown, Green, Yellow, Gold
2.4Meg = Red, Yellow, Green, Gold
820 = Gray, Red, Brown, Gold
150 = Brown, Green, Brown, Gold
