Product details
Soviet FEU-82 photomultiplier tube.
One tube in one lot.
The tube is sold as "for parts", because prior history is unknown and no tests were performed.
The tube is in good condition, but it may either be working, or not.
We ship via Standard International Airmail from Kyiv.
Tracking number is provided.
