I am redrawing many of the Grebe schematics. The new versions will include voltages, part numbers, and values.
I am also creating original mechanical drawings of some components. These will facilitate creation of modern replacements if vintage parts are not available.
This is an ongoing project, so check back often, and request anything you need that's not already here.
And for more about this neat radio, check Dave's great Synchrophase site.
