JINRO

The Jinro is a Pure Class A Singled Ended valve amplifier that uses the highly regarded 211 triode valve, producing a level of performance that is radically superior to the vast majority of current designs.
 
 
 
It uses the same circuit design and topology as the legendary Audio Note ONGAKU amplifier. However, where the ONGAKU uses silver wherever possible, such as for all transformer windings, the JINRO instead uses copper.
 
 
 
It has been specifically engineered for sonic performance rather than technical specification, and fulfills all Audio Note Level 3 criteria:
 
 
 
Pure Class A operation
 
 
Zero Negative Feedback
 
 
Single Ended Output Stage Valve Rectification
 
 
Directly Heated Triode operation Materials and component quality
 
 
 
 
As with all Audio Note components, the Jinro is completely handmade, including the point-to-point wiring. The proprietary power-supply choke and drive-stage transformers are labors of love—the sorts of thing one sees less and less these days, in any field of endeavor.
