Vintage Simpson Model 555 Vacuum Tube Tester. Great Condition. For Repair

Description

This unit is in great physical condition and has only been opened up for the pictures of the inside.
Internally it looks like it is in good and factory condition.
It probably needs some work though.
It powers up, but that's as far as my testing went.
I haven't tried to test any tubes with this, selling as is.
Feel free to ask questions.
Thank you for your interest.
I have more vintage electronics as well as quality tools in my other listings.
