OK, I plucked up courage to plug in with all the valves removed, and a 40W bulb in the tester. These are 75 Ohms measured cold, and must be more if lit up. The transformer hummed quietly, and the bulb lit dimly, with about 35V across it, leaving 90 or so on the transformer primary.
I let it soak for a few minutes, and there was no change, and no sign of anything getting hot, making odd smells or smoke. Output voltages were about right if you take the 90 V input into consideration ~315-0-315 on the HT, ~4 v on the rectifier heater socket and a little over 5V on the other heaters.
Oh yes, and more wood glue...
Other things to do here in the mean time, but at this point things seem ready to complete wiring (dial & shadow meter assembly) and go for a careful test. I'll post more if I get there.
