Finally, with the help from my girlfriend, I manage to get the Nuvotem Talema Transformer on hand within a week. It’s rated at 6.3A with 2x18V output or about 225VA. Not bad for my LM1875 huh…
Another beautiful picture of it.

November 30, 2009 15:41Toroidal power transformers are so rare (even Stancor do not manufacture them), and expensive too. I have salvaged many power electronic systems, however managed to find only one in a studio quality power amplifier made in England.
Answer me a question and make me grateful. Why you preferred the use toroidal transformer in power supply application (at low frequency)? With my experience nothing compared to your majestic expertise, I custom wound a high quality E-I frame type power transformer rated at 25V 20A. Why did not you?

November 30, 2009 21:19Hi,
Toroid is not that expensive. And we can get some advantages, like lighter weight, smaller dimension, low interference/low noise, etc, comparing with EI design.
It’s not easy to get high quality EI cores in my country, and also not easy to get good solid copper wire.
With this current situation, I would rather go with the toroid.
Thanks.

December 1, 2009 16:36The points you highlighted are stone sturdy. However, I may never get access to one in my country. Thanks for the reply.
I have been fascinated by your quality control from day one. And the enthusiasm to take up challenges that researches would run away from. And success in this field demands quality test and measurement instruments. What instruments (brands and models) do you use? I would use your answer as suggestion and advice.
I am pursuing post graduation in Electronic Instrumentation. Your reply will have me obliged.

I’m just a DIY, don’t own sophisticated stuff. But sometime and luckily, I have access to such “not too bad” equipment – but definitely far from sophisticated.
Thanks.

Menurut pengalaman ko Jimmy, apakah trafo berpengaruh banget terhadap warna dan kualitas suara seperti misalnya kalau kita menggunakan filter capacitor yang berbeda?
Thanks

March 31, 2011 21:15Hi,
Efek trafo bagus sangat terasa pada suara, walaupun bukan memberikan warna seperti capacitor.
Thanks.
