Up for your consideration / auction is an Vintage Lambda Power supply LGS-6-15-D-0V-R AC-DC switching power supply. Please read this description and review and examine all the pictures before placing any bids on this item. I have had this power supply in my possession since 2000. I bought this for a project that I never did get around to doing. It has been inside of dry storage of an warehouse for the past 12 years, I have not used it. It is made in Melville, L.I., NEW YORK from the back information plate lettering of silk screen printing that was done at the factory. This power supply is in very nice condition. It has been lightly used, with only some scratch marks on the bottom from being moved around in it's storage days. There are a few scratches on the top left edge of the case from being handled and that is all of the marks on the other sides of this case that I could find. The front panel is in nice usable shape with all the hand tighten screw on terminals present and the Phillips/Standard-head screws are all in great shape with no rounding out of the heads of the screws. The voltage adjustment screw works and does limit how high the voltage goes as you adjust the screw. The only thing I could find wrong is that are a few areas on the front face where the paint has worn away and the metal is slightly exposed and you can see this in the photos of the front face. All the sides of the casing seems to be in great shape with some small marks , there is a few areas where the factory paint has come off and there are a small bit of surface rust on there areas, please see the photos.. The front of the case has a terminal block. It looks to have been used lightly as there there is only a slight amount of dust. All the ventilation holes on the top, side, and bottom are all clear and clean and are not damaged in any way. There are no burn marks or heat damaged paint anywhere on this power supply. There are several sets of mounting holes on the front,side, and bottom of this power supply, made of course to mount it inside of a rack or other mounting equipment. This power supply is currently wired for 120 input Voltage operation and has a wire connection plug for standard 120 Volt plug into the wall. This power supply was tested and found the, voltage only, to be in working condition. I am unable to correctly test the current output of this power supply, as I do not have a way to properly load test it, I will have to list this as partially working, or for parts only.
