Audiophile Z11 Power Transformers

These are special custom made audiophile Z11 power transformer for tube amplifier (filament supply). It is not cheap but definitely is worth the investment. The wires used are UK made silver plated OFC with Teflon insulation.

The secondaries are drawn out directly using the same wire materials instead of via solder-tags then with other types of wires. For those that might not be aware, there is a reason for such designs. Different wires have different characteristics impedance. Once you go though a change of materials, that equals to change of characteristics impedance - see below:

On DC world, it looks like this:





* Wires A - connector - wire B

On AC world, especially on high frequency operation, it looks like this:
* Wire A (impedance A) - connector (impedance C) - wire B (impedance B)

What happens when the impedance change? Reflections, attenuation, boosts, and all sorts of artifacts of impedance mismatch. This will indirectly affect the signal integrity of the music signal. At audio signal range, it should be negligible but every little things matter.

It's better to take every precaution possible, and therefore the birth of this special made audiophile Z11 power transformer.

Of course, we will not forget to share some pictures! Enjoy!
