This 1965 Telefunken 6DJ8 / ECC88 tube was made in West Germany. It has the following characteristics:
  • gray risers
  • round shield with two raised rectangular sections on opposite sides
  • halo getter with wide, angled support post
  • white label with diamond Telefunken logo printed between "Made in Germany"
  • diamond imprint in glass between the pins 

This tube tests as new with balanced sections. It has been screened for gas, heater-cathode leakage, shorts, and excessive noise and microphonics. It was tested at typical operating voltages on a laboratory grade Amplitrex AT1000 (manual setting, fixed bias mode). Learn more about our testing process here. See product options for current availability.

Noise and microphonics

Tubes that test as "phono grade"--the quietest range for noise and microphonics on our custom noise testing equipment--are an excellent choice for sensitive applications such as microphone preamps, DA converters, and phono stages.

This tube is sold individually. It ships in a new white box with test results for current draw (mA) and transconductance (Gm) for each triode section. Matched pairs, when available, are listed as Item 468.
