Excellent clear thorough video,surprised you didn't fit the secondary side resisters to get rid of over shoot ringing? Is it not better to loose a little gain in order to have perfect response? Also do all these factors translate to what transformers actually sound good and the monetary values asked?
You indicated that the Hana cart would have required a loading resistor in parallel with the outputs. Did you put one in and did it make any difference?
I saw a warning printed on a transformer about testing with a multimeter, and the possibility of damage from the test current. Is this really possible? I have an auto ranging digital multimeter. Is the warning perhaps related to the older style analogue instruments?
You named the series, “Building a step up transformer” but all you did was, saying that you were going to build a car, than giving a lot of background about how internal combustion engines work, and after the theory, instead of building a chassis and an engine, you bought a second hand car and replaced the tires.
It would be nice to show, how close one can reach the performance of the vintage step-up transformers, using the materials and manufacturing methods which are available to the public today. We regard the material to be the most important aspect of the vintage SUT performance, is it really the case today? I have built Ultra-Linear output transformers for Class AB amplifiers in the past and I know the importance of selecting high-quality material, but I have also learned how sectionizing influences the leakage inductance or the criteria to decide between different core designs or how to lower the input capacitance to extend the frequency range. My transformers were not as successful as the ones that I have tried to reproduce and I always thought that I haven't flipped all the stones. I still think that SUTs are small, therefore they are the perfect vehicle to carry on a demonstration on how close one can get to the performance of a vintage SUT by employing the basic rules that you have mentioned in the theory section.
@@oturgator it is definitely not the material, more likely the arrangement of the windings. Different conductors being used, say silver vs copper vs gold, only have different resistances. And copper has the lowest resistance. That's why "audiophile cables" are a scam, no matter what way you slice it, it's just a wire.
Once again, another very informative and practical guide. It will be great to hear how it went with the Hana!
Very helpful, your video was beautifully presented
Own several of Ned Clayton's Transformers. Fit and finish is 1st rate. 👍

Nice box, but my OCD would go into overdrive with the transformer labels not being "square" :)
May I ask what happened to the loading resistor?

Nice!!
Hi how you doing! Just wondered if you know any website where I can download a PDF file on tube testers charts thanks!!
nice grounding loop ;)
Was there ever a Part 4 listening test?
Can you do a similar video for an autoformer? Maybe even build a diy autoformer?
👌
This is not about a building but rather about assembling a box. Like for dummies.

Did you want me to wind the transformers?
Now that would be pretty intense!
