[Elecraft] KPA500 Air Flow Space Concern

[W0UCE]

I am rebuilding my station console and would like to put a wooden shelf
above my KPA500 but am concerned about blocking air flow to the top of the
opening on the top right of the amp.   The KPA will sit on the operating
table desktop with the front raised using the bail.  If I put a shelf over
the amp I can cut an opening for airflow space if necessary.

 

If anyone has experience or suggestions regarding minimum space for airflow
I would appreciate your input.  Contact offline if you prefer. 

 

Thanks,

Jack
