Description
Famous triple micas version !
This pair of Siemens & Halske E82CC tubes, made in the Siemens & Halske plant in Munich Germany. They are triple-mica E82CC with copper posts on halo getter; one of the finest E82CC. The E82CC is a premium version of the ECC82. The etch codes on the glass of the tubes indicate that the tubes were manufactured in 1971. The tubes have triple mica reinforcement plates and a round halo getter on copper post. The tubes have excellent test values that match the factory specifications very well and balanced systems.
The properties of this tube are widely known. I refer to the many threads on the web for more information.
The tubes have NOS test values that match the factory specification very precisely and they have balanced systems.
Sonics
Excellent valve, low noise, low microphony, very good in phono stages.
E82CC: balanced, detailed and clear sounding with liquid midrange, recommended!
