Up for your consideration / auction is an Vintage Pyramid Regulated Power Supply Model PS-9KK. 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 7-29-1999. 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 13 years, I have not used it. It is made in China from the front information sticker printing that was applied at the factory. This power supply is in very nice condition. It has been lightly used, with only some scratch marks on the back and front 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 Standard-head screws/bolts are all in great shape with no rounding out of the heads of the screws/bolts. The only thing I could find wrong is that are a few areas on the front face where the paint has worn/scratched 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 two wire connection terminals. 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. The plug in cigarette terminal is in great condition with no burn out marks or deterioration from use it is in very nice shape. The ON/OFF LED lit rocker switch works great with a positive motion and a firm click from one position to another. There are no burn marks or heat damaged paint anywhere on this power supply. On the very end of the molder plug there is a few marks. I have taken a photo of those marks to show that they are cosmetic in nature and do not effect the operation of this power supply. They just are not pretty in nature. The plug end and the rest of the power cord are in very nice condition. 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 to be in working condition.
