Matched quartet of KT66 GEC early types with clear glass made in Great Britain and more so the 4 of them come with CUP getter, see photos. Valves or tubes that last and due to cup getter they produce better sound! You do not see them that often!
It's a buy it now auction but I do not accept low offers since tubes are strong!
This CUP getter batch was named EU by GEC. The CUP getter version is then the CV1075!
Among the best valves you can find for your vintage or modern amplifier.
These 4 pieces KT66 have been tested with closed current output of 74mA; 75mA; 76mA and 76mA which means all of them give full emission with good mA/V which as you can see goes down the scale of the tester showing a FULL 6.3mA/V for each valve.
Stunning KT66, the best!
Happy Bidding. I will ship worldwide and can ship multiple items. Please consider holidays and some delays. Thanks for watching.
