Perhaps there has been a little misunderstanding over the LED. There is no problem with fitting an LED to indicate the equipment is on but why run it at 10 to 20mA when most LEDs will be quite happy at 5mA. At a lower current the batterries would last longer.
When I wrote constructional articles there was never any question of "Does it actually work", I think they assumed it did and it would have been a lot of effort to check every constructional project. Only one magazine wanted the finished item and that was only for photographic purposes.
