Manufacturer: SED

This vintage Svetlana 6H13C dual triode power tubes in this precisely matched pair are Russian 6AS7G tube types popular in OTL and headphone amplifiers (these have all been auditioned in a Bottlehead Crack headphone amp). They were made in St Petersburg before the Svetlana logo was purchased by New Sensor. They have black plates and dual bottom getters with lots of flashing. The label has the "Winged C" logo.


Both tubes test as new with very low noise. They have been tested at typical operating voltages on a laboratory grade Amplitrex AT1000. This testing process also includes screening for gas, heater-cathode leakage, and shorts. They have also been screened for noise and excessive microphonics in our OTL headphone amp.
