My fiances father passed recently and she collected his things. Amongst them is some various radio equipment that I have been looking up. I haven't been able to find anything really about this power supply/amp/pre amp. I hoped possibly I someone here could possibly point me in the right direction. It says its a super star 500 base station power supply amplifier. Has a pre amp built in, at least thats what the switch on the front says. I was trying to find the specs on this particular one but there are no model number plates on the device that I can find. Anyone have one or possibly familiar with this particular unit? I would appreciate it greatly. Google has only shown me some partial cached pages for a few that were for sale and one post on this site. It looks like this one here http://www.worldwidedx.com/cb-radio-gear-swapshop/92420-super-star-500-base-linear.html and I'm basically wondering if the specs quoted are the same.
