RCA 6AS7G - black plates
Price: $47.00
Item Number: 1175RCA
Manufacturer: RCA

This 1957 RCA 6AS7G dual triode power tube was originally intended for use as a series regulator, but it is now used in OTL and headphone amplifiers. It has black plates and a top getter. The silver print on the base has the RCA logo.


This tube tests as new with low noise. It was tested at typical operating voltages on a laboratory grade Amplitrex AT1000 (manual setting, fixed bias mode). This testing process also includes screening for gas, heater-cathode leakage, and shorts. This tube has also been screened for noise and excessive microphonics in our OTL headphone amp.

Price is for a single tube and includes standard testing and matching service. Tube ships in a new white box with test results for current draw (mA) and transconductance (Gm) for each section.
