Oscillator

[scs]

Perfect working oscillator. Tested.

[homefire]

Nothing is ever PERFECT ! LOL

[scs]

For this oscillator is we can say.Do it and make sure.

[scs]

Improved variant.

Improved variant.[ATTACH]46515[/ATTACH]

Now it's even more perfect

[scs]

Sometimes there is even better than good. Did you discover anything? why do you laugh at things you do not understand? xxxxxxxxxxxxxxxxxxxx

I don't know anything, well, I can draw schematics that don't hurt the eye, милая моя.

This "perfect" and "improved" oscillator will destroy the transistors by applying a reverse Vbe voltage of 20V. Maximum is 5V.

The schematic is part of a detector that works.C2=C1=100nf.C8= 1uf.L=9mH,DD coil.F= 7.5Khz. I do not want to deal with empty heads.

Dear Teleno,
You need to know that the transistor breaks through the current created by reverse voltage. In the circuit this current is small. You can use for toilet paper your diploma.

It works. For a while. The current gain of the transistors will quickly deteriorate.

Congratulations for this clever design!

By the way, the PCB is just as neat as the schematic.

The gain is current enough, the circuit starts working even at very low current on the transistors base.

Try this. Simpler, more powerful, low Veb.

[scs]

Not more powerful,Q factor is very high.
