Description
The late 1960s Siemens E83CC tubes in this precisely matched pair are premium quality 12AX7 / ECC83 tubes. They have gray plates and halo getters. The white label on the glass reads "E83CC" and the Munich, West Germany factory code is etched in the glass.
Testing
These tubes test as new. They are precisely matched for both current draw (mA) and transconductance (Gm). They have been screened for gas, heater-cathode leakage, shorts, and excessive noise and microphonics on each triode section. They were 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 matched pair. Tubes ship in new white boxes with test results for current draw (mA) and transconductance (Gm). Singles, when available, are listed as Item 792.
