Speaking as someone with much experience here, the "hole" should always be bottom!

But, but - they are upside down! The bases will come out with the wrong phase


If you look very closely at the picture, he manufacturer agrees. It's my wife who had to be reckoned with. In fact, if you look at some of the Amazon Q&A for wall outlets this seems to be a popular question "Can these be installed the "right" way" :)

Due to the lack of interest and/or skill of people here, I have closed my For Sale ad and will assemble the item in question.

And, no, the assembled unit will not be up for sale.......

Finally finished casing my Blue Hawaii today. Running on my "universal" PSU that also powers my HV Carbon.

400VDC and 18VDC rails, 20mA plate current. The heatsinks warm up to about 42C (108F) and stabilize, about 22C (40F) rise from ambient temperature.   

The chassis is a Breeze Audio 3608A, one of 5 chassis I bought from Breeze Audio at TaoBao. I requested that the front and rear panels be left plane, un-drilled. Works quite well.

Very nice!

Low voltage +/-18 volts, right?

Yes, the GRLV 18VDC rails are for the 2SK170 front-end.

Fogless misting system for my mill :)

I'll be able to turn this on and off from the milling software via the solenoid on the left (below)

All joking aside, no particular reason really. It's DIY and I like to tweak and experiment.

18V is well within the operational spec of the 2SK170/LSK389 and other associate parts.  I happened to build a 18V GRLV for my SS Dynalo and decide to re-purpose it and build 20V GRLV for the SS Dynalo instead...

Is that some new SI unit of measurement? We Americans don't always get the memo on what the rest of the world is doing.

It's actually only 45.63 minivolts, but this slightly odd conversion factor is probably the main reason why the minivolt isn't commonly used :rolleyes:
