Hi Brooke and others!

Have a 6624A and a 6622A. Have yet to arrange a good front panel for
their outputs. 

The thing that bothers me is the rather large amount of noise they
generate. The fan is LOUD compared to my other instruments.

Anyone done a safe conversion on the fan solution to these nice beasts_

I have a more powerful DC electronic load, but I almost never use it. Its only drawback is its size - rackmount - which makes it a bit large for small benches. In my case, I made room for it!
