Not me, I have too many power supplies now. But,
As they have remote voltage sensing and you need a panel anyway why not connect long cables to put them under the table or where the noise is less of a concern. As a plus you could have more space where you need it and the flexibility to have a more mobile panel to move around the room. I have no idea about cable size or max length but it should be listed somewhere.

Hi Brooke and others!
Have a 6624A and a 6622A. Have yet to arrange a good front panel for
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!
