Tokyo, Japan     Possibly One of the Best Sounding Output Transformers Ever Built As Good as Tamura or Tango, or Better   With 21st Technologies  Based on 60 years of Sansui Experiences       Introducing the Hashimoto H-20-14U:   The Hashimoto H-20-14U is for applications that require 10K or 14K Ohms primary with up to 20 Watts output level into 4, 8, 16 Ohms.  The H-20-14U is equipped with an Ultra-Linear tap for both 10K and 14k Ohms primary, and its frequency response covers between 30Hz and 50,000Hz (+-3db) - please click the right thumbnail to see the actual chart.  The H-20-14U is called a universal type because it can be used under 10K or 14K Ohms of primary through separate B+ terminals.  Since the H-20-14U has separate B+ terminals, it also has independent Ultra-Linear taps for each primary impedance.  The H-20-14U is suitable for single-ended applications that utilize popular vacuum tubes, such as 6V6, VT-62/801A, 42, 6F6, AND VT-25/10.  Because of this versatility, the H-20-14U is one of the most popular transformers among Hashimoto's amazing lineups.    The H-20-14U measures 88 (W) x 80 (D) x 110 (H) mm, and weighs 2.4Kg (5.3 LB).  The Primary Inductance can be chosen between 40H/50mA (10K Ohms) and 50H/45mA (14K Ohms).  The Maximum DC Current can be up to 80mA.  The H-20-14U consists of a double Cut-Core in the shell type.  The core material is 0.27mm Orient Core Hi-B, which is the enhanced directional silicon steel, from Nippon Steel Corporation.  Hashimoto engineers has intentionally avoided to use permalloy or amorphous cores for sonic reasons.  Please refer to our Hashimoto Transformer Technical Aspects page for more details on technical details as well as Hashimoto Product Design Philosophy.                              As being mentioned, the Hashimoto H-20-14U is one of the most popular output transformers that Hashimoto Electric, Ltd. in Tokyo Japan introduced in 2002.  Today, Hashimoto products are regarded as one of the premier tube amp transformers among Japanese hi-fi enthusiasts and columnists who originally introduced the sound of single-ended amplifiers in the world during1980’s and 1990’s.  In fact, some of most influential columnists have been switching their favorite transformers of their choice from Tamura or Tango, to ones with Hashimoto brand, such as the H-20-14U.   Who is Hashimoto Electric anyway?  Hashimoto is by-no-means a new comer in this very traditional, but exciting industry.  Hashimoto Electric, Ltd., in Tokyo Japan has been a long-time Sansui transformer OEM (since 1960’s).  Hashimoto merged Sansui’s transformer business in 1978, and Hashimoto was the company who reproduced the AU-111 transformers when Sansui reissued the famed AU-111 in 1999 as the AU-111 Vintage.  As a matter of fact, Hashimoto is the only company that still carries the original Sansui logo on its product lines, and some of Hashimoto’s key engineers are ex-Sansui engineers.    Today, Hashimoto Electric produces not only various traditional transformers that Sansui pioneered many years ago, but also high-end tube amp transformers under its own brand name.  The amazing thing is that all Hashimoto transformers are still handcrafted one-by-one by very skilled and experienced employees (Please refer to the actual photos I took when visited Hashimoto last June).   Because some of Hashimoto engineers have more than 40 years of transformer designing experiences through out Sansui and Hashimoto era, all Hashimoto transformers still maintain the superior characteristics and sound of Sansui transformers.  In addition, all Hashimoto transformers are redesigned from the ground up.  This means that Hashimoto transformers are the 21st Century products that have been fine-tuned with computer aided programs and have utilized new materials that were simply not available forty some years ago.  As the result, the H-20-14U is one of the leading Hashimoto products that have been winning reputations among critics as, "The sound through Hashimoto transformers simply belongs to a different class compared with that of competitions."         Should you need a pair of H-20 class of single-ended output transformers in different impedance, such as 2.5k, 3.5k, 5K, OR 7K Ohms.  Or smaller class, such as the H-507S (7W, 5/7K Ohms) or H-203S (7W, 2.5K/3.5K Ohms).  Please let us know.  We will import them, and list them on eBay.                                     Who are we?  We are a Michigan based corporation being in the IT related business since the early 1990's.  We have been exploring the web based business opportunities since 2002, and today we are the authority of Sansui literatures with more than 1,000 customers.  Almost all of our Sansui literature business have been conducted through web space for the last three years.  Now, we are expanding our horizon into the hi-fi hardware business by introducing the best products available in the world.  Because our business is entirely based on the web space, our priority is nothing but the customer satisfaction and customer support.  Please purchase our products with confidence.          Should you have any questions related with this product or our existing business, please don't hesitate to send us an e-mail at support@obsinc.us.
