@forty2 That is a sweet setup.

@forty2 All that space to walk around behind the shelves is absolute genius. I am very very impressed. Congratulations!

@forty2 Nicely done indeed.

What do you do for electrical - one 15A circuit for the whole space, or a few? Are your power strips on separate circuits?

Love the rear-access to all the gear. So user-friendly.

@ottaross I ran 2x 120V 20A circuits each on their own home run, on opposing legs. There are 3 quads in the ceiling, one at the corner, and one at each end, each with both circuits, so I can plug in power strips in to either circuit & leg. Right now it’s all on one circuit, and I may run the whole thing through a 20A variac just to knock the line voltage down from 125V to a more geriatric gear friendly 115V or so.

@forty2 nice. Good flexibility.

@forty2 @ottaross

To get a reduced mains voltage without the need for a big variac, you can use a 125V mains-powered transformer (e.g., filament transformer) with secondary/secondaries in series with mains to take away some voltage. This scheme entails kVA proportional to the voltage dropped (e.g., 12.6V) instead of the voltage supplied (e.g., 125), thus 10x less iron. It does not result in isolation, but isolation wasn't the stated goal.

@antonio @ottaross oh woah, neat trick, thanks! I actually have a pair of 20A variacs that I’ve been lugging around the planet for 30+ years, but I’m gonna play with your idea ‘cause it’s such a neat hack :)

@forty2 Love all the rear space for cabling and for the fans to breathe. <3

@forty2 Very nice! I wish I had that kind of space!

@forty2 Wow, that's super impressive So much organization. And the space behind, just wow.

@forty2 That's beautiful!

Send follow up pictures once it develops a lived-in look... or a plea for help if it ever starts to look like mine! :-)

Oh very nice.
Also, HP 4195A?

@ftg yep! Was for sale just down the road, too cheap to pass up. Seems to work OK, though I’m not super versed in the dark arts of RF.

It's very low lower edge of 10Hz means it's also excellent for analyzing regulator control loops.
My unit still has sticker on it declaring in Finnish that it's from the power supply division of some unnamed company.

@forty2 @ftg I've used those for loop gain measurements all over the place.
