Toroid Transformer

We have received considerable requests from customers on providing high quality toroid transformers. We are not really a supporter of toroid transformer but there are just cases where EI or C core transformers cannot fit. Therefore, J&K toroid transformer is born, just before April Fool's day! 

Toroid transformer winding method is totally different compared to EI or C core transformers as it does not need bobbins and requires machine to do the work right. Investment alone on the automatic winding machine is hefty! 

As usual, we only offer high quality cores, and our toroid cores are high quality customized cores from Nippon Steel. Due to the nature of how toroid cores are wind, we highly recommend the toroid transformer to be potted and filled with potting compound to keep it mechanically stable, for sound quality and longer life.

Normal grade toroid transformers rattles and have very obvious noise, especially when it is loaded. This really gives audiophiles a big headache. If you are sensitive to this and want a truly quiet fully rated toroid transformer, this is the one to get.

  • <500W toroid transformer is about 130-150mm D x 75-97mm H with cover 
  • 1200W toroid transformer is about 159mm D x 110mm H with cover.
  • 1500W toroid transformer is about 180mm D x 120mm H with cover.
  • 2500W toroid transformer is about 210mm D x 120mm H with cover.

When you order, please specify the voltage needed on what conditions - no load, half load or full load. They are built with 24x7 operation in mind - industrial + audiophile grade! All transformers are meticulously tested, with primary being flashed with 4KV for 1 minute.

Nippon Steel cores are quiet on empty or full load. Our design guarantees that it will not make noise at full rated load! We have two types of toroid cores too - flat 90deg and doughnut (smooth O, better) ring (600W, 800W and 1000W only).

Applications:
  • Single ended or balanced isolation transformer
  • Power transformers (single ended or balanced) for solid state amplifiers or tube amplifiers (1Vac to 1000Vac)
Indicative price is as follow. Please contact us for actual price with your specific requirements and specifications.
  • 500W - U$200
  • 1000W - U$300
  • 1500W - U$400
  • 2000W - U$500
These are high grade toroid cores, winded with high grade copper magnet wires, customized per customer needs and therefore will be pricier than standard toroid transformers. As far as I know, even the small time manufacturers will only do so for customers with MOQ (minimum order quantity) of 10 units. We accept even 1 unit! 

For those that requires low power applications (<500W), we usually recommend EI or C core transformers. For high power applications (>500W), toroid transformer becomes more economical option to consider. Coupled with the lower stray magnetic field compared to EI or C core, it is something audiophiles should not forget. With the potting and shielding from the case, making a low noise high power solid state amplifier becomes a reality.

If you have been considering to make isolation transformers for your beloved HIFI gears, this is the time to do so! You can use toroid isolation transformers (balanced output if possible - better!) for your power amplifiers, and EI / C core isolation transformers for your low power gadgets like preamplifiers, CD Player or DAC. Each equipment should have their own isolation as the equipment themselves are noise generators too. Having individual isolation transformers serving individual gears will give you much better isolation and much lower noise (darker background) comparing to sharing a same huge isolation transformer.

Now, send us your wish list and we will do it for you! If you have wanted your own isolation transformers similar like those used in BPT, Equitech, Isotek and such, now is the time. You can DIY it yourself, or have us custom make one in a proper chassis for you. An example below is posted for your reference.






P/S:
  • We only supply high quality products and that comes with a price. If you want to search for low cost or negotiate for very low price, please look elsewhere. We cannot satisfy this type of requests. 
  • High quality products take time to be built. If you want fast delivery, please consider twice before ordering from us. We will provide a lead time estimate upon ordering and we shall try our best to meet it but it is not guaranteed.

3io’s BlackBox Application Notes

How do you use the 3io's Blackbox? Click on the link if you do not know what 3io's BlackBox is.

The amazing part of this 3io's Black box is, it works, very obviously, as soon as you connect it to your equipment ground. Once you have it connected, you will NEVER be able to take it down again. It is an outcome of ages of experimentation and listening test, after rested multiple materials, to arrive at the best formula.

Function 1: 
Decompression of soundstage, especially with dynamic complex music. Deepens the depth. Increase the strengths.

Function 2: 
More analogue, more feelings. Reduce sibilance.

Function 3:
Darker background. Darker black. Quieter quite passages. More details. 

Function 4:
Absorb EMI/RIF and improve the SNR of the system. 

Note: some systems will have more and some will have lesser effects, depending on the "health" of the existing system.

Applications
  1. Recommended - screw tight on chassis (remember to connect electrically as most chassis are anodized and insulated). It is best to have all equipment in the system connected to the BlackBox.
  2. Ground your anti-electrostatic brushes to increase the effects.
  3. Connect to the ground pin or negative pole of your speaker outputs (if it is not bridged operation).
  4. If your gears are high powered complex electronics, sometimes several BlackBoxes will bring better effects by paralleling several units to a single equipment.
  5. Connect it on your wall socket ground pin near your HIFI system.
  6. Connect it near your noise generating equipment - fan, TV, microwave, fridge to prevent noise from propagating further to other places. 
Tips:
  • Try with different points on your system to get the optimal effect. 
  • Try with different cables, clips and spades - the higher quality, the better the effect.
  • If you cannot locate any ground posts or grounded screws, try clipping it on the RCA exterior connector or metal shield of the USB port.
  • IT NEEDS RUNNING IN! It takes about 10 days to stabilize. The effects will vary within the first few days of running it. Please bare with it for 1 week or so.
The effects of connecting it on the chassis is that it will widen the soundstage, dig out more details, better the clarity, relax the sound, increase the separation, reduce the digital effect (more analogous).

Reason being
  1. It reduces the electrostatic charges/potential, giving the chassis and ground plane a regulated potential.
  2. It reduces the free electrons floting around the ground plane, causing lesser effects to the micro-electrical currents.
Q&A
  • Q: Do I still need it if I have active or passive filters on my mains?
  • A: Yes. This is not a filter.
  •  
  • Q: If I have a mains filter, how should I connect it?
  • A: 1 - connect it on your equipment ground directly. 2 - connect it before and after the mains filter. 
  •  
  • Q: What is the effects of paralleling the BlackBox?
  • A: It strengthens the effect. Do note that there shall be an optimal quantity for your gears. Try to increase it 1 by 1 until it brings negative effect, then step down 1 unit to reach the optimal quantity.
  •  
  • Q: Will it restrict the dynamics?
  • A: No. It is connected in parallel. It is not in the direct signal or energy flow path. It does not change the flow of signals.
Warning:
  • It does not and cannot replace the ground / Earth line.
  • It needs running in and settling down.
  • It does not need to be discharged or energized.
  • Connect to the dedicated ground post of your equipment for best effects.

Enjoy!

3io’s BlackBox



We are distributing 3io's BlackBox (ground treatment device). Take a look at the description below. 

3io’s BlackBox


Increasing use of domestic electrical appliances inevitably introduces more on to the power line. This pollutes the mains leading to significant degradation of audio and video performance.


Shielding, filtering and isolating helps “clean up” the sound up and improves the sound quality significantly. This technology is best-shown or used in audio cable manufacturers. If DC resistance and shielding are the most important factors on power or signal transmission, then there won’t be much variations of audio cables in the audio industry. 


Stray electrons are highly undesired in the world of Audiophiles. What are the ways of reducing all these stray electrons? Some examples would be to use non-conductive materials like wood where some of the manufacturers are excelling in using wood as sound tuning materials. Instead of solid plate of metal, some uses conductive film technology on a non-conductive material to provide shielding but not creating excessing mass effect.


A dedicated ground treatment will help by creating a stable potential on the equipment to keep the free electrons number under control by channeling them to ground at a constant rate. Due to the advancement in technology of today, polluted ground or combined grounding in an condominium . apartment is making matters worse. After an extensive research done and countless tests conducted on  virtual ground, we are proud to introduce 3io’s BlackBox. This device will help draw and collect free electrons and keep them under control, preventing them from polluting the signal transfer. 3io’s BlackBox acts like a black hole, drawing any available matter into it. 


Each 3io’s BlackBox will be able to control a quantifiable amount of free electrons. How many units are needed per system is dependent on the amount of free electrons present in the system. It has to come in balance the amount of 3io’s BlackBox units to be used. Users will have to determine themselves based on their listening evaluation. 

The effects? Simply amazing. Darker black. Quieter background. Lower noise. Lesser sibilance. Increased transparency. More seductive mid-range. More extended highs and solid bass! You have got to try it.

This is the chassis we are going to use to house the device




 Here are some of the applications examples using our prototype boxes:

Connect to amplifier ground pin/pole


 


Connect to CD Player / Transport / Source Ground

Connect to PCB ground


Connect to ground of power distributor

Connect to wall plug



Connect to voltage regulator ground pole

Plug into voltage regulator socket

Connect to voltage regulator ground pole


Pre-order (introductory) price - U$149 (offer until Mar 2015, limited to 12 units only)
Retail price - U$229 (April 2015 onwards) U$299 (Dec 2015 onwards)
 Email us now to secure a unit. Delivery is expected to be mid - end of April 2015.
