No, but it limits the current

Precisely why I used 10k, for safety.

if you just feel tiny something on 3000 hz it might kill you at few hz frequency !!! I tried!

I don't doubt it. Fortunately you survived to tell the tale

 

Hmm, after reading this TRULY FASCINATING report on Rife
http://rifevideos.com/chapter_9_1938_to_1939_beam_ray_corporation_clinical_rife_machine.html
(this is only chapter 9, I suggest reading all the chapters and videos on main page) I wonder how to do the following:
1. Get 1,604,000.00 hz square wave (50% duty cycle) OR sine wave. 40106 is unfortunately not able to pass 400,000 hz and that is with severe drop in voltage and transformation of signal to something like sawtoth. I will try opamp lm6172 but I doubt it will do better. Any ideas ?
2. I would like to "modulate" 40,000 hz frequency onto carrier wave which is 3,2mhz (I bought 2 pin crystal for that). This is like FM radio modulation to get many side bands or harmonics every 40,000 hz above and below 3,2mhz. Problem is there is no 4 pin crystal oscillator for this frequency and I have to do with 2 pin version which is only crystal without amplifier and all else.
I found circuit how to add capacitors, resistor and amplifier but I need extra information how to modulate that with 40,000 coming from 40106.

3. Rife was obviously using AC current with AC circuit components. As this is DC low voltage current and I don't have access to spectrum analyzer does anyone have idea will this crystal oscillator modulation give decent (and how many) side bands or harmonics every 40,000hz from 3,2mhz ?
Example how 3,8mhz carrier wave with harmonics look like

You guys were great in helping so far.

 

Hmm, found LTC1799 which can generate square wave up to 33mhz with only 1 resistor circuit !
FM 3,2mhz modulation is still troublesome...
