Corona Sphers part number H49-0026  
 
Porcelin posts are welded inside of the power supply and are not replaceable.
The porcelin posts are designed to prevent surface tracking of the high voltage
electricity. However, dirt and buffer dust will collect on these posts, which may cause
the operator to hear a loud band noise. To clean the posts use a clean dry rag.
