content: I'm a beginner. I would love to build one from a kit, but the kits I've seen don't include a meter of any kind.I watched the review of Dave blowing up the Korad power supply. Looked like a winner up until that point.Anyway, If the bugs have been worked out of the Korad, that would be great. I'm in the USA so 110VAC.I'm looking for something like a 15VDC variable, with an amp or two. Nothing fancy, just accurate and solid.thanks

content: Quote from: wblackledg on July 07, 2013, 12:21:28 amI'd go old school, much better deals to be had. For example,hereis an HP 6114A with the 10turn current set pot for ~$100 shipped. Note, he takes Best Offer so you can likely get it for under $100 pretty easily.This PSU is a work of art to be sure. Here is my thread and tear down on this PSU:https://www.eevblog.com/forum/testgear/hp-6114a-precision-power-supply/msg227582/#msg227582Mucher higher quality than the new supplies (very tight regulation and precision). Plus 0-20V 2A or 20-40V 1A.or look for the Power Designs precision supplies.Like this oneThese are also VERY reliable and VERY stable.

content: If you are willing to pay 100,-€ the ELV Prozessor-Power-Supply is a good choice. It's available as a kit:http://www.elv.de/prozessor-netzteil-pps-5330-komplettbausatz.htmlIts big brother is the dual supply and costs twice the price:http://www.elv.de/dual-power-supply-dps-5315-komplettbausatz.html

content: ELV PPS5330 is worth the money.I own two of this power supplies and there are only few things to notice:-Frontpanel Keys that come with it are cheap, I soldered some better keys from an old laser printer. Original ones will work, too.-the fan makes a little noise when the supply is on load, but it isn't that annoying. But for fans of passive-cooled power supplys it is the wrong deal.The behaviour under load is quite good, the user interface is great when you like the concept of changing single decimals. Output Current limit is accurate enough to drive even LEDs oder laser diodes for a short test. I had no problems at the 3A Limit, it does its job.You should buy the kit, because the finished device has only average building quality (esp. soldering).

content: These seem to be the instructions in German:http://www.elv-downloads.de/service/manuals/PPS5330/PPS5330_KM_G_080303.pdfIt seems you are not in the northern part of Italy otherwise you probably would have know a bit of GermanAnyway, its not for the faint hearted and it needs adjusting after building. I'd buy a readily made (second hand) PSU from Ebay or the local classifieds.
