Replace the power switch with a DPDT switch. The LED and a battery can be turned on with the second pole.

The power switch is a double-pole switch. It switches both (floating, independent) filament batteries. There is no high voltage switch - when the filaments are cold, no current is drawn. (This is the way battery radios from the forties often worked.)

I guess the previous post should read triple pole double throw switch.

That's also a good way to do it. That way you aren't messing with the original circuit.
Thanks
