another small breakthrough on our NERD technology.

TK,

Thank you for taking time to test this.

>>Negative bias meaning I supply negative polarity to the point in the circuit where the FG's "positive" connection is made, right? And then >>"positive bias" means I supply positive polarity at this point.

Yes, the above is correct.

>>In brief: my version of the circuit does not oscillate when supplied with DC from the 9v battery+10K combination instead of the FG.

My circuit does oscillate in your 2 case. Try another main input voltage, like 0 to 12 volt, and see if you get any oscillations.
I never get any oscillations with a positive bias.

GL.

Well. That's interesting.

My FG has the capability to provide a DC output, varied by the offset control in the same manner as before. When I use the DC output of the FG, I get steady oscillations, with or without the batterypack, when the DCvoltage from the FG is offset to a certain value, both in the positive and the negative direction.

So, my circuit does oscillate when given DC from the FG, both positive and negative biased, but at different values.


ETA: OK, I tried with an adjustable PS. I get the exact same results as with the 9V battery, no matter what the applied voltage. That is, the same +2 VDC for positive bias, and -0.6 VDC for negative bias, from 0 to 15 VDC applied at the FG location from an external PS, plugged into the common ground.

So my circuit only wants to oscillate when it's hooked to the FG. I have another, less sophisticated signal generator, the WaveTek VCG Model III, that I can try as well.

TK,

Put your variable power supply at the battery input of your circuit and keep the 9 volt
battery (with 10K in series) at the BIAS input.

Oh...OK, I misunderstood. I'll give it a try.

I tried the WaveTek just now and it produces the same oscillations as the F43, but I can't vary the offset or provide straight DC with the WaveTek, only can vary the output voltage... but it behaves the same as the F43 when I reduce and increase the power.


ETA: OK, I tried it using the Elenco XP-581 variable PS hooked into where I had the 3v pack before. I get the same results, except instead of the battery voltage I see whatever I've dialed into the PS, from 0 to 20 VDC. No oscillations when using the 9v battery as positive or negative bias; the same oscillations as before when I use either the WaveTek or the F43 FG. The LEDs light better, even when I just have the PS turned on but no output voltage.
My circuit likely isn't the same as yours: I have the LED in parallel with a relatively heavy inductor in the load. But I've found that the value of the inductor doesn't seem to change the behavior much.

TK,

Thank you for providing the test.

You probably need more inductance to get the oscillating going without the function generator.

Thanks,
GL.
