Done, no pics.

Executive Summary: Ignore the dead bulb or seek out an OEM spec replacement.

The Jaycar bulb SL2685 can work, but it took a lot of fiddling. Basically it’s too long, even when carefully trimmed. I completely dismantled the panel and removed the AC button, from it I took the clear diffuser and shaved off 3mm.

Being brittle, the white plastic “chassis” of the control panel lost a couple of clip legs. Now re-fixed with dabs of urethane, all globes test correctly.

A sneaky problem with the clock illumination, the epoxy protectant over the circuit board was stopping the new bulb’s contacts from correctly meeting the conductive tracks. I built up the contact area that engages with the bulbholder flange using a thin layer of solder. Old school but gets it done!
