Matched quartet of KT66 GEC early types with
clear glass made in Great Britain and
CUP getter, see photos. Valves or tubes that last and due to cup getter
they produce better sound!
They do not turn up that often!
It's a buy it now auction but I do not accept low offers since tubes are strong!
CUP getter version is then the CV1075!
Among the best valves you can find for your vintage or modern amplifier.
4 pieces KT66 have been tested with closed current output of 74mA;
75mA; 76mA and 77mA 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+mA/V for each valve.
Stunning KT66, the best!
Bidding. I will ship worldwide and can ship multiple items. Thanks for watching.
