Right, I understand. I have switched off any sleep function in my test
clock that has been running 24/7 so the clock won't shut down when the
room is unoccupied and I'll come back in a few hours and check. The test
clock has the acrylic columns cut at 45 degrees compared to 22.5 degrees
in the photo, so more of the back of the E1T is covered.
Back later...

The ones I have that get hot do it closest to the base where the heater wires
enter the cathode and where they aren’t shielded. It looks like the round
acrylic tube is very close to the E1T, that’s the part I wondered if it was too
close.
