NOS/NIB NEW Siemens E88CC/6922 O-Getter Made in Germany with Gold Pin. Labeled as Pinnacle. This tube is quiet, but microphonic. Verified by lightly tapping on the chassis and tube. However, there is no microphonic feedback from speakers in my system when left alone or playing music in my system. Not recommended for phono stage or microphone, or any other sensitive application. This tube should work well in most Buffer Stages of DAC output/preamp output. If you find it too microphonic in your application after purchase, you may return for full refund. Please select "Didn't fit" for the reason for your return. No international shipping. Date Code: A4 9A Made in January 1969 in West Germany. Fully tested by calibrated Hickok 539C tube tester with no shorts, leakage or gas. Measurement: 14900/14500 where minimum good value is 7000 Very tightly balanced and very strong tube! I will gladly combine shipping upon request.
