This 1963 Dario Miniwatt E188CC / 7308 tube is a premium 6DJ8 /ECC88 type tube. It has the following characteristics:

This tube tests as new with balanced sections. It has been screened for gas, heater-cathode leakage, shorts, and excessive noise and microphonics on each triode section. 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

This tube tests as "phono grade"--the quietest range for noise and microphonics--on our custom noise testing equipment. It is 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.
