Ray at the 'Radio Workshops' in Worthing specialises in restoring and selling DAC90A radios for a living, and when restoring them, converts the dial lights to 6.3V by fitting a small transformer. That of course requires that the value of the shunt resistor needs to be changed or there is a risk that the valve heaters are over-driven. This mod ensures that not only are bulbs more widely available, the lights do what they're supposed to do - light up the dial.
The thing about the DAC90A dial lights (in the context of the DAC90A the term 'light' is something of an oxymoron), is that even if you can find the right bulbs, the dial is dimly lit. Some say that this is simply a characteristic quirk of the set, but really, what's the point of dial lights that aren't fit for purpose?
