Test Results:



This Ei 6DJ8 / ECC88 tube was made in pre-war Yugoslavia (the label on the tube reads "Made in Holland," but the factory code in Yugoslavia is etched in the glass). It has the following characteristics:
  • creases on the top of the bottle
  • dimpled disc getter with A-frame support
  • silver risers
  • white label
  • Ei factory code etched along the bottom of the glass

Tube tests as new. 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

Noise and microphonics

These tubes are graded for noise characteristics
on our custom sound testing equipment. The grades range from "driver" (low noise/microphonics, but still suitable for use in low sensitivity applications such as driver tubes in an amplifier) to "preamp" (very low noise/microphonics) and finally "phono" (selected for the lowest noise/microphonics--these tubes 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. Photo is a sample from the lot.
