Repairing a soldering iron (transformer type): tips & tricks & more

Описание: The video tells everything that is important. A talk about repairing a soldering iron. Correction: on 13.02 I say “210 Volt” (AC, mains) but of course I mean: 110 Volt (AC, mains). Sorry for that.


When, I in the final moments of the video, I talk about "transformation losses" in terms of voltage & current and say that they are in the "10% to 20 % range" it could be that it was somewhat overdone. 10 % loss is (on average) real in this frequency band (50 Hertz-300 Hertz) .


But it could also be that the transformation losses are less, say in the 8 % range. That depends a lot on the quality of the used transformer(s) in terms of magnetism, reversed-magnetism, properties about dumping energy, etc.


Please note: we are talking here about energy transformation in the 50/60 Hertz & 230 Volt or 110 Volt AC range. A completely other story and parameters compared to the electronic situation is (say) on 50 KC or 80 KC. That situation needs another electronic/electrical approach.

There are more than 1200 Video’s on my YT channel. I only do analog electronics: audio amplifiers, analog measuring devices, radio circuits, many Shortwave radios, many oscillators HF and audio, other audio & shortwave circuits. Also many (test) generators for all kinds of waveforms, both in the audio range and HF.

Also simple “switch” circuits like the Schmitt triggers acting on different input voltages, 555 circuits and circuits of basic electronics issues like “Ohms law”, resistance properties, capacitance properties, the capacitors testing process, electronic “matching” in audio circuits and audio amplifiers, audio pre amplifiers, microphone amplifiers, etc. In all cases you find the schematic inserted in the video.

When you have questions about (certain analog) electronic circuits and how to make them: go to my Channel trailer (Radiofun232 on You Tube) and go to the “looking glass”. Type there the keywords that you want/need like: “power supply”, audio amplifier, capacitor tester, oscillator, radio, shortwave, shortwave radio, or any keyword you like to find the essential info & schematics on my YT channel.

You can contact me via email when you have questions about my published circuits. I always ask for a picture of what you have made + a problem description; I ask to communicate. When you don’t want to communicate please don’t ask help. Sorry that I am so strict now (since 15 may 2021). It has to do with disappointing reactions in the recent past of people that asked “help” (even fake help) and did not react afterwards or asked questions when they knew the answer.

My You Tube channel trailer is here:    • Radiofun232 on YouTube, find working & tes...   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”, “amplifier”, “filter”, “Shortwave”, “transistor”, “FET”, “oscillator”, “generator”, “switch”, “schmitt trigger” etc; so the electronic subject you are interested in. My books about electronics & analog radio technology are available via the website of "LULU”, search for author “Ko Tilman” there.

I keep all my YT videos constant actual, so the original video’s with the most recent information are always on YouTube. Search there, and avoid my circuits that are republished, re-arranged, re-edited on other websites, giving not probable re-wiring, etc. Some persons try to find gold via my circuits. I take distance from all these fake claims. I cannot help that these things happen. Upload 20 september 2021.
