In order of likelyhood:
Poor tube pin to socket (Wiggle them a little while playing, see if the volume changes) Clean and retention the tube sockets, and tube pins.
Out of range resistor that goes further out of range or opens when the set warms up. There aren't very many of them, and they are cheap and easy to replace. Replace all of the carbon resistors in the power supply and audio output sections.
A diseased mic capacitor in rf or if section. They may be hiding in the IF Coils. Again, cheap and easy to just replace e.
Other (coil opening up or cold solder joint, grime remaining in one of the adjustable trimmer capacitors)
Other other ?? Have to work backwards from the speaker. Somewhere between the speaker and the antenna there is a problem.
