Description

The 1977 Mullard 6DJ8 / ECC88 tubes in this precisely matched pair were made in Great Britain (Blackburn, UK factory code) and have the following characteristics:
  • creases on the top of the bottle
  • dimpled disc getter with A-frame support
  • silver risers
  • red print on the glass with the Amperex logo
  • Blackburn, UK factory codes and matching date codes etched along the bottom of the glass
Testing

Both tubes test as new. They are matched for both current draw (mA) and transconductance (Gm) on each triode section. These tubes are screened for gas, heater-cathode leakage, shorts, and excessive noise and microphonics. They are 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 test as "phono grade"--the quietest range for noise and microphonics--on our custom noise testing equipment. They are an excellent choice for sensitive applications such as microphone preamps, DA converters, and phono stages.
 
Pricing

These tubes are sold as a precision matched pair. Tubes ship in new white boxes with test results for current draw (mA) and transconductance (Gm) for each triode section. Photo is a sample pair from the lot.
