It depends how you feel about 'authenticity' but I'd delighted with the LEDs I fitted to my DAC90a and they were cheaper too. The only down side is that they just come on bright and stay bright so you don't have the fun of the light-level changing as it warms up.
It seems strange that the radio won't work without lamps in as mine did while I was working on it and sorting them out was the last thing I did. I'd have a look to make absolutely sure that all is well with R18 (that's the Trader sheet number; it's R16 on the Bush service sheet) which is the left-hand green one on the panel with the voltage adjuster.
As for the voltage/current thing I think you're right but you'd need enough voltage to push that current through the filament. We're getting into the theoretical realms where always did get lost.
All the best
