Orient Hi B C Core

Orient Hi B C Core (Cut Core) Output Transformers 

What? J&K has new stuff again? Nuh, not really. This Orient Hi B C Core (Cut Core) is what we called it as Super Hi B C core. For those that followed us since 2014, they would have known that we have this excellent laser strip Hi B C core that are used to make output transformers, chokes and transformers. 

Orient Hi B C core is just another name, used by mostly Japanese manufacturers, such as Tango and Hashimoto. That also proves that, Orient Hi B C core, or Super Hi B C core, is an excellent material to be used for audio transformers. You can re-collect our past posts here below on these high grade Orient Hi B C core transformers:

Why are we bringing this up again here? We brought good, no, GREAT news! We are lowering down the prices of transformers made with Orient Hi B C core (Super Hi B C core)! It was previously ONLY used in our Level 2-3 transformers and were quite out of reach for some folks, but now we are making them at Level 1, which means that the pricing will be following Level 1 pricing!

- Size: depends on complexity 

* Above are transformers with bare square or L frame. Potting requires slight addition to the transformer prices, from U$30/pc++, depending on sizes. 
* Sizes may vary, depending on incoming C cores. 
* Level 1 transformers CAN be made with OCC (Ohno Continuous Cast Copper) wires. OCC copper wires are expensive, but is well worth the money! 
Power transformer and choke prices are not listed. Their prices depends on the complexity and design parameters. Email us. 

Why do we constantly push out new stuff? Here's out motto: 


Promote vibrant custom-made HIFI industry! 

Imagine, how much more you can do, how much better you can get, how different you can be, with more high quality, uniquely custom made transformers from J&K!

Internet references, taken from pictures from the internet - "Orient Hi B Cut Core" can be seen on the label of the transformers for Hashimoto and Tango / ISO Tango transformers.




By the way, does anyone know why there's such a stain near the top of the tube?
