Yes, the Ranger is a very FB transmitter. It's my favorite AM commercial transmitter.
Two years ago I tried to decide between buying a clean Ranger and modifying it heavily, or building my own version from stratch.
I ended up building my own "Commando," a two-6146 plate modulated transmitter good for about 90 watts carrier out. The modulator is a Chinese 140 Watt solid state module driving the biggest Hammond mod transformer available. All self contained including power supply and modulator. Below is the link to the entire project on AMFone.
It is one of my best efforts for a smaller rig and it works flawlessly, 150% positive peaks and 20 - 15KHz audio. The project gets very interesting later in the thread.
Maybe it will give you some ideas. Good luck with your Ranger endeavers!
