OK you MSR-2000 guys... there's a Manual available on Ebay... it's the Station Control Manual, which is the Service Manual for the Modules (Cards) in the back plane (chassis) but you should have this book along with the matching RF Manual for your repeater service needs. The smart way to go would be to have the other two RF Manuals, one for VHF and the other for the UHF Package as I believe only the VHF RF Manual has the Power Supply information unless you have a special version of the book.
