I have one pair of closely matched Takatsuki 300B tubes for sale.
These tubes have LESS than 200 hours (I meticulously keep track of hours used) and furthermore I had the tubes tested by a highly knowledgeable tube man on a calibrated TV-7 tube tester.
The results were 90 and 91 when 58 = 65% of useable life. Thus these tubes are shown to be meeting new or above new specs and virtually an identical match to each other.
These tubes have been handled with the utmost care and will be shipped in their original factory custom box as shown in the pictures.
i will offer a 30 day guarantee on these tubes which will hopefully give any buyer peace of mind when making a rather expensive investment in tubes. This guarantee only covers defects in the tubes relating to working properly. It does NOT cover breakage due to misuse by the buyer nor does it cover personal taste issues such as "I don't like the sound of this particular brand". If tubes are returned I will cheerfully return you money once they have been tested to verify that they are defective with respect to test results. If they are not proven to be defective in that sense then no refund will occur.
Please check my perfect feedback over the past 15 years on A'gon and purchase with confidence.
