Finally restored my AC-3 so I can start on the TR-3. Prognosis is good...works on most bands and sounds pretty good.
The other BA is the Heathkit mobile twins I picked up at Deerfield. The Comanche is very much alive; might only need alignment.
The TR-3 power requirements are very compatible with the Heathkits. Now...gotta restore the almost basket case DC-3 I got at the same time.
