Details:

Worked when last used by my husband but I am unable to test as he passed several years ago and have no idea what I m doing. It does power up normally lights come on and needle moves. Knight tube tester with instruction manual. 38K165 so I assume that's the tester model.

The manual says stock no. It also says part no.
