Скачать или смотреть Universal Voltage stabilizer and hum suppressor circuit schematic

Universal Voltage Regulator between 8 V and 50 Volt to charge batteries and/or supply electronics that need a constant voltage, max 4 A at 12 V and 1 A at 50 V. Also useful as hum suppressor (50 Hz-60 Hz and sometimes more) circuit for sensitive audio (pre) amplifiers. The video speaks for itself. The transistors MUST have the indicated current amplification (Hfe), otherwise problems can be expected. So test the BD 139 and the 2N3055 first on Hfe.

In thematic order you can find these video’s under the “comments” section.
Important: to find all the links to the (+/-700) video’s on my YT Channel, select, in the comments section, “NEWEST FIRST”

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. Upload 3 august 2018.
