This is the first in a series of videos in which I will be demonstrating Ferroresonant Transformers and explaining how they work.
I’ve studied a little about power supplies I’m a novice for a hobby but I’ve never heard of that power transformer and it’s purpose and benefits. I build linear audio amplifier power supplies for amplifiers I build. We were always taught just use a bigger transformer and more capacitor Power bank. Example if you Project called for 200 VA transformer use a 600 VA Toroidal transformer. I can’t wait to see how this project turns out looks like I have a new transformer to acquire and play with.
Another very informative video - thanks!
You’re aware that the input banana jacks are not 4mm but 4.2mm. Voltlog discovered this.
Have you noticed the mains induced hum on your videos? In this video, it is increased when you touch the toroidal transformers and the power supply case. Is it magnetically induces, or mechanically coupled? Thought you might want to check and ‘rectify’.
Check the audio during the first part of the video on a high quality entertainment system. I am not referring to the obvious mechanical noise of the ferroresonant transformer. I have noticed this background hum on many of your past videos. It is not obvious on iPad or iPhone with no low frequency response.
I’m glad that my iPhone filters out that disturbing hum. 😉
please let input voltage stable
I have a old power supply that has a ferro transformer. It has a annoying buzz sound so I don’t use it. I put it away on a storage shelf.
Useless demo.

Looking forward to learning how it works. That is rather amazing!
