Product details
Used Soviet 6E5S magic eye tube indicators.
Two tubes in one lot.
Tested on L3-3 tester.
The tubes are lit at ~70-80% of maximum brightness.
We ship via International Airmail from Kyiv.
Tracking number is provided.
Any questions are welcome.
6E5S is not 6E5 tube and cannot replace it!
The electronic indicator light for indication of tuning in radio receivers, radio stations, indication of recording level in tape recorders, is successfully used to indicate the signal level in the tube ULF.
It was used for indicating tuning in radio receivers, radio stations, recording level indication in tape recorders. Now it is successfully used for signal level indication in tube ULF. Indication is carried out by a circular sector of green color through the canopy of the cylinder.
