Parasitic oscillations in Audio and HF amplifiers; how pro prevent them (schematics & instructions)

Описание: Sorry: quite a long video but in my opinion instructive for all electronics hobbyists and professionals. Video about how to prevent and cure parasitic oscillations in audio and HF amplifiers. Many remedies are showed and explained, both regarding audio (AF) and HF. Both regarding pre-amplifiers and (audio) end-amplifiers.

So when your audio (pre- or end-) amplifier that you made so perfectly starts to scream or oscillate when you turn the volume knob or the sound-correcting knob to the maximum, go to his video and (perhaps) it can help you.

Better said: it surely it will help you.

Important: approx 50 % of the homebrew electronic circuits (audio and HF Amps and self-constructions and experiments) suffer from this problem (oscillation= instability that can easily be cured by the methods showed in this video).

Thus solved by the “wonder” word: “decoupling”. Both in an electromagnetic (shielding metals etc.) or electronic sense (decoupling capacitors with decoupling resistors in the power supply lead).

In thematic order you can find these video’s under the “comments” section. My books about electronics are available via the website from “Lulu”, search for author “Ko Tilman” there.

My books are also available via Barnes and Noble and via Amazon. Regarding all my video’s: I constantly keep them actual, so the original video’s with the most recent information are always on YouTube. That is the source, and search there. When my video’s are reproduced or re-edited on other websites/channels you can not (!) be sure about the original content (=really working electronics) and important adaptations to the circuits.
Be aware of that, I saw on the internet many of my circuits reproduced in a poor or even not proper way. I can not help that, sorry.
