Price: $149.00
1 matched pairs in stock
Item Number: 712HP
Manufacturer: Amperex

The 1969 Amperex 6DJ8 / ECC88 tubes in this precisely matched pair were made in Holland (Heerlen factory code).
Both tubes have the following characteristics:
  • creases on the tops of the bottles
  • the Heerlen factory code and matching 1969 date codes etched in the glass
  • silver risers
  • round shield with two raised rectangular sections on opposite sides
  • dimpled disc getters with wide support posts
  • white HP label with "Made in Holland"

Both tubes test as new with balanced sections. 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.

These tubes are sold as a precision matched pair. Tubes ship in their original 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 80.
