Description Technical Specs
 
Tubes are from May 1977 production, even though the generic printed date on the certificate is 1976. With Tungsram Industrial tubes, it is common to find differences in the date code on the tubes, and the generic year when the paper certs were printed.

5 of 5 Great tubes! August 19, 2021
Reviewer: Jonathon from SC, USA  
I purchased a pair of these for my Cayin headphone amp. They are excellent in this application. Very smooth mids and excellent vocals in both male and female ranges. Both ends of the spectrum are extended, but not overdone. No sibilance to speak of. Low frequencies are tight and controlled. Overall a very dynamic tube that is pleasing to listen to(typical of Tungsram). I am using with an OTC amp and headphones that have an impedance of 25 ohms at 1kHz and 100db/1mW sensitivity. These are very revealing headphones and the tubes are very quiet with them. I am very happy with this purchase and I highly recommend.
