I already had a monster blower on hand when I put my YC-156 amp

the cooling fan on my PC makes here in the ham shack.
### I learn something new every day ! I never tried remoting a
blower. I had been told that a lot of the noise was from the
actual airflow through the tube itself, so never tried it.
With the 4cx3000A, most of the noise comes from the exhaust side of the variegated anode cooling fins. The sound made is similar to wind blowing through pine trees.
