Lot of 3 Telefunken 12AT7 ribbed plate tubes, diamond on bottom, all are strong!
£84.66
Lettering ranges from strong to not really there, but you will find the tone and the long life you need for these. Great in an amp or tube microphone! You get all three! Minimum on my TV-7 is 50, and these test at 90/88; 72/65 and 70/76.
