Manufacturer: RT

This 1965 12AU7WA tube was made by La Radiotechnique (RT), the French subsidiary of Philips Holland, which also owned Amperex and Mullard. It has gray plates with copper grid posts and a halo getter with wide dual supports. The green label has the RT logo and the Radiotechnique factory code is etched in the glass. 


This tube tests as new with balanced sections. It has been screened for gas, heater-cathode leakage, shorts, and excessive noise and microphonics on each triode section. It was 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

This tube tests as “phono grade”—
the quietest range for noise and microphonics—on our custom noise testing equipment. It is an excellent choice for sensitive applications such as microphone preamps, DA converters, and phono stages.


This tube is sold individually. It ships in a new white box with test results for current draw (mA) and transconductance (Gm) for each triode section.
Matched pairs, when available, are listed as Item 515. Photo is of the actual tube.
