Made in 1964 by Radiotechnique/France factory of Philips. All tubes are in pristine condition and have same factory codes. These have double stage O-Getter.
The ECC189 was designed for VHF tuner intputs in TV sets as PCC/ECC189, used briefly in the early 1960s in Europe. A risk-free, pin compatible alternative to ECC88/6922 tubes, but with variable mu. It will perfectly serve as cathode follower as well.
Interesting tube for DIY'ers, manufacturers and those who want to experiment. Matched pairs available.
Price : US$26.00/each
