Description

The late 1960s Amperex 6DJ8 / ECC88 tubes in this precisely matched pair were made in Holland (Heerlen factory code) and have the following characteristics:
  • creases on the top of the bottle
  • halo getter with wide support post
  • silver risers
  • orange print on the glass with the Amperex globe logo (missing)
  • the Heerlen, Holland factory 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
phono stages, microphone preamps, DA converters, and other sensitive applications.
 
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. Singles, when available, are listed as Item 744.
