Hickok CA-5 Adapter
Good functional unit, clean inside and out.
Bought this NOS and used it maybe a half dozen times at the most. Very nice clean CA-5
 
The tube data for this unit depends on what Hickok tube tester you will be using it with. The CA-5 data can be found at Bama and elsewhere, but if you have problems finding it, I can provide it in a PDF file via email.
