ECN Forum Forums General Topics of the Trade General Discussion Area OT- B.727 Com Radio

I know it's OT, but...
I recently bought a Com radio from a Boeing 727 (VHF Air Tranceiver... Scrapped from plane, no cosmetic damage, $25, no big loss if it doesn't work). It's still on its way from Panama. I was wondering if anyone knew where I could find specs, mainly voltage. I googled it, but came up with nil.
Thanks,
Josh
