Using Inexpensive Line Transformers For Vacuum Tube SE or PP Output Transformers

Using the inexpensive audio line transformer for SE and PP vacuum tube audio amplifiers and how to determine the plate-to-plate load and center tap. For reasonable plate load impedance values these types of line transformers are going to be low wattage. These transformers might be ideal for headphone amplifiers and similar applications where low wattage is adequate. Here is a very nice article that includes schematics posted below by a viewer. http://www.ozvalveamps.org/optrans.htm More further reading at the bottom of the article: https://www.bunkerofdoom.com/lit/modt... Keep in mind that in most of his examples he uses a 100 volt line transformer rather than the 70.7 volt transformer that I used in my video. When working with these transformers keep in mind that squaring 70.7 gives 5000 (as I used) and squaring 100 gives 10,000 so a 70.7 volt line transformer at the 5 watt tap would be 1000 ohms but the 100 volt line transformer at the 5 watt tap would be 2000 ohms, etc.
