Germanium 1 transistor audio pre amplifier (the basics to get it working properly: demo & schematic)

Please read the description first. Video about a 1 Germanium transistor audio pre-amplifier. How to get it working properly. SORRY for the sudden stop (!), my camera stopped, and I don’t know why... Though everything important was told. Thanks for watching.

Two basic potentiometers are used: a 25 K for the biasing and a 1 K potentiometer in the emitter lead of the transistor to ground (it sets the amplification, of course never more than the transistor can give, for Germanium often in the 70 x range with a good and healthy one, some go to 100).

That AC (read: audio, say 20 Hz-20 KC) amplification (the frequency band where it works, in this case 20 Hz-20 KC) is set with the value of the capacitor that goes from the wiper of the 1 K potentiometer to ground. Here I used 10 uF, that is (say) common for 20 Hz-20 KC. You can also use 0.47 uF (non polar) or 0.1 uF (non polar). The usable frequency band will shift/depend.

IMPORTANT:
Because I was/am shadow banned and censored by You Tube/Google during the past 2 years and the past 2 months (severe) because of my critical comments regarding the anti-Covid mRNA jabs from Pfizer & Moderna, here (again) an update about the Covid situation in the Netherlands.

A) The propagation of the (mRNA) jabs in the direction of Dutch youngsters by the Dutch State goes on. Nothing is told to the children and youngsters (12 year and older) about the possible side effects. They use a Tik Tok approach. In the past (autumn 2021) they imitated the song “this girl is on fire” from Alicia Keys with “this girl is on Pfizer” (advertisement campaign in the direction of youngsters in the Netherlands, happened 2021).

B) The past week (as far as I know 24 or 25 sept 2022, ) there was a Court hearing in the Netherlands, at the Court in the Hague. The procedure regarded the fact that the Dutch State (presented by the RIVM, the Dutch authority for Health and Environment) refused to give the data about the “oversterfte” (=excess deaths) and refused to give the (calculation) model that they used to access/assess the Covid effects to the Dutch population during 2019-2020-2022, in terms of expected infection, fatalities, etc.

C) These (up until now 28 nov 2022 ) hidden models are important in relation to the measures that were taken by the Dutch Government in those (2019-2022) days (and even now): lockdowns, closing shops & restaurants, lock out unvaccinated people from restaurants, clubs and sport facilities, closing theme parks for the unvaccinated, pressing fines and measures to people that were on the street during the lockdowns, fines to doctors that have given medicines like hydrochloroquine and ivermectine, etc. And an enormous economic damage to shops and restaurants in the Netherlands (and the MKB). All these measures by the Dutch state were based on models of the RIVM, but the RIVM refused (up until now, 27 november 2022) to give the models on which they based their ideas and issued the measures.

Now the Dutch Court in the Hague is asked to give a verdict about the refusal of the RIVM (Dutch State) to give the data and the models. Please note: when you search via keywords (Dutch) on Google you will find nothing about this Court procedure, Google hides the links to this procedure. It is part of the censorship that Google and the Dutch state have been agreed (prove: WOB/WOO documents, also published via a recent Dutch Court procedure, initiated by journalists).

The Court procedure was attributed by the “Biomedische Rekenkamer”, litt. Translation: a chamber (“foundation”, in Dutch a “Stichting”) with biomedical scientists/actuarissen that study scientific models and modelling in the field of biomedical issues.

The Court in the Hague will give a verdict on 20 December 2022 (as far as I know now). Link: (Dutch)    • De Biomedische Rekenkamer vecht voor openb...  

In Germany: approx 1100-1200 procedures are started (in courts and some procedures outside German courts) regarding the damage cause by the mRNA jabs. Source: DW (=Deutsche Welle, mainstream media channel on YT). Link is    • Видео

When you search, search always “NEWEST FIRST” to get the right overview. You can also search via the “looking glass” on my Channel trailer via keywords like ”audio”, “radio”, etc. etc. My books about electronics & analog radio technology are available via the website of "LULU”, search for author “Ko Tilman” there. https://www.lulu.com/search?adult_aud...

I keep all my YT videos constant actual, so the original video’s with the most recent information are always on YouTube. Search there & avoid my circuits that are republished, re-arranged etc. on other websites. Some persons try to find gold via my circuits. I take distance from all these fake claims. I cannot help that these things happen.
