Rectifier Tube TA-274B

Commitment to ultimate made-in-Japan quality, refusal to compromise

Takatsuki Electric released the TA-300B in 2010 after the absence of new domestically produced audio vacuum tubes for 35 years. The TA-274B rectifier tube is our second made-in-Japan audio vacuum tube we developed by maximizing our technologies and knowhow accumulated in the creation of the 300B.
The TA-274B delivers the ultimate vacuum tube quality that only Takatsuki Electric, the one and only vacuum tube manufacturer in Japan, can offer.
