[NLRS] NEED 24-28 Volt Power Supply

[christenson at charter.net]

I have picked up a Military T.E. Systems 225-400 MHz amp that has a power req. of 24-28V DC. 10W in 100W out. I am going to use it on 222. 

I need to know what would be an adequate amperage for a power supply and some information on building a pass band filter.

Anyone with a 24-28V power supply for sale or where I could find one CHEEP or any ideas on how to build one please let me know. Also the infor on low loss pass band filters

Thank You,
