[Elecraft] Samlex 1223 Schematic and Parts List

[Tom Hammond]

Hi Folks:

For those of you who happen to have the Samlex 1223 OR the Kenwood PS-15 
12VDC 22A switching power supplies, here's some information which may prove 
to be useful to you sometime down the line.

I have placed on my website at QSL.NET (http://www.qsl.net/n0ss) a PDF 
containing both the schematic of this power supply and the parts listing. 
It's currently at the bottom of the contents list.

So far, I have no service information, but I'm hoping to get some in the 
future. If I do manage to find this info, I'll add it to the PDF and 
re-post availability here.

A WARNING - These power supplies are NOT(!) transformer-isolated from the 
AC mains. As such, they can be DEADLY to anyone who is working on their 
innards without adequate knowledge of what they are doing or if they are 
careless with regard to where they place their hands or test probes. BE 
VERY CAREFUL when attempting to service switching power supplies... and 
these supplies are no exception.

73,

Tom   N0SS
