December 25, 20169 yr Author comment_750204 But, but - they are upside down! The bases will come out with the wrong phaseIf 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" Report
December 26, 20169 yr comment_750302 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....... Edited December 26, 20169 yr by wink Report
February 5, 20179 yr comment_754418 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. Edited February 5, 20179 yr by mwl168 Report

February 16, 20179 yr comment_755736 1 hour ago, joehpj said: what's the difference between 15V and 18V? 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... Report
February 16, 20179 yr Author comment_755740 = 3000 minivolts 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. Report
February 16, 20179 yr comment_755746 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 //UFN Report
