I picked up a Viking ranger that does not have the grid block keying and modulator screen modifications.  I cannot find the earliest version of this transmitter schematic to match my version of the transmitter.   I want to restore to original specs, then choose to install select mods.  I have found several good sites for restoration, but I still haven't found the pre Ranger 1 and Ranger 2 schematic.

Any help is appreciated.
