Testing the TK Tar Baby

Mags,

The 50R should be in series with the FG + lead.  There is no Q2 bias current limiting as you have it.

Hey Pico

Well, if the resistor is in series with the gen, then the gen has not 50 from sig lead to gnd.

If the 50 Ohm resistor is in series with the positive terminal (as is the case), then "looking back towards" the FG from the FG + and - leads, one "sees" 50 Ohms resistance.

What you've drawn is 50 Ohms in parallel with the output, and that is not correct. If you looked back towards the FG in your case (and there was no other resistor installed in the FG), then you would "see" some very low impedance, perhaps on the order of a few Ohms.

Ok. I thought that alll the talk of this meant that there was a current path through the 50 ohm res in the sig gen.

If internally, the 50 ohm res is just simply in series with the signal, then the current path is available, when?

So here, I imagined that the res path was available at all times in the circuit. If it is only available to the circuit part time, is the problem that when the path is available, the source voltage over powers signal voltage? Or is available when the sig phase is off?

Sorry bout that. I guess not seeing it visually, I took what was being said as I did somehow. ;] As you can see.

I am working on a FG anatomy diagram. Will post it shortly.

The current path through the 50 Ohm is there at all times.

@All,

I see that .99's and TK's single Q2 oscillators are being endorsed as being "overunity", as she refers to it.

If only TK would use a rechargeable battery...

I wonder if .99 is using "rechargeable" batteries in his sim?

Possibly, when/if .99 posts his "overunity" oscillator over there he can show (again) how current flows thru Q2.

She continues to believe that Q2 somehow "floats", and I do not believe she is referring to the positive portion of the FG cycle wherein Q2 is turned off.  In spite of all manner of discussion and evidence to the contrary, she believes there is no path for current to flow thru Q2 during the negative voltage portion of the FG cycle.

As well, it seems she is just going to bury her head in the sand regarding Q1 not turning on in FIG3 and FIG7 and ignore the whole issue.

It goes on and and on and on...
