This Collins 516F-2 Winged Emblem, Power Supply, has a 115 / 240 VAC Primary and can be wired for either voltage at 50hz or 60 hz. (It is currently wired for 115 VAC.)This power supply is in good condition. It is a late unit, serial Number 62013, and the production number is MCN 8241.The cabinet has the original paint and finish and looks great. There are a few minor touch ups on the cabinet with matching paint. It also has a metal trim ring. The proper aluminum risers and original Collins feet are Included. This Power supply works and has the original electrolytic capacitors which should be changed if intended to use it on a regular basis. I have Capacitor replacement kits available and can provide one at my cost. In addition to the dual voltage capability, it has a longer cord that goes to the KWM-2 transceiver, or 32S- transmitter. This power supply has been tested with a radio, and I have checked all of the voltages with no load, and then under load to make sure it is within specifications, and will include that data. This item must be shipped in two separate cartons or the cabinet WILL get damaged. I will remove the chassis from the cabinet and ship it separate from the cabinet, tubes and feet. The shipping cost reflects the cost for two boxes.I will include a professional reproduction of the manual.I am very proficient packing this type of heavy vintage radio gear. The unit will be double boxed and professionally packed to a degree you can not get from normal packing facilities.
