Here is my 1T4 radio, James.
It doesn't get a lot more simple than this. It is meant for shortwave,
but by changing the coil and tuning capacitor, you can make it work on
the MW band pretty easy.
Many other circuits you see around will work with 1T4 tubes, so long as
you adjust the filament and plate supplies to match the tube. I would
recommend that you use a circuit that uses a filament tube, rather than
one with a heater and cathode.
Start with a one tube radio, and leave room to add another.
