No,

Tim's original 3mm LEDs had 470 ohm reistors giving a 15% overload at 14.2V
The 560 ohms on page 7 came from a random ebay image.

I surrender, Robert !!

The resistance was measured with a modern digital meter, and also looks identical the the one M Gilligan shows – 470 Ohms

*******

I pointed out that ‘identical’ and 470 were not consistent; but receiving no clarification, assumed that either the resistor value must have changed or it was mis-marked.

Clearly I mis-understood the word ‘identical’

Mea Maxima Culpa
