In September 2018, I lamented the demise of Noguchi Transformers. Fast forward to November, my brother-in-law visited Tokyo, and was kind enough to pick up a couple of transformers at Kasuga Wireless.
How to get to Kasuga Wireless

In the past, I've used Hashimoto transformers for a pair of SE2A3 and a pair of SE10 mono-blocks I built for friends. I know these transformers are well designed, are of high quality construction and sound excellent. Thus, before Hashimoto ceases production, I had to add it to my collection.
My mono SE2A3 integrated is ready for prime time!
Dear sir,
ReplyDeleteI really envy you, you have very good music equipment.
Can you tell me how to contact Hashimoto Transformer to buy their products？
Thank you.
Best regards,

I don't think Hashimoto deals directly with consumers. Try this dealer if you are based in the US -http://www.tube-amps.net/index.htm Good luck!

Dear JE,
DeleteThank you for your suggestion.
I am from HK, I have contacted with Mr Asakura of tube-amps.net.
Thank you.
Have a nice day.

You mention before they cease production. Is this likely to happen?
ReplyDeleteMy buddy John P. is making the rounds in Japan right now. He'll give us an update on the status of transformer manufacturing there.

Hello.
DeleteJust a comment for other readers.
Hashimoto is still working. I ordered a couple of transformers from the ebay store. They also provide customized power transformer manufacturing services.
Please check my latest blog entry which talks about the Hashimoto HM7 MC transformer - https://jelabs.blogspot.com/2022/04/mc-step-up-transformer-redux-hashimoto.html + John Piro's trip to Tokyo -https://jelabs.blogspot.com/2020/03/our-man-in-japan-jp.html
