This is a simple LED backlight modification for the Sony ICF-SW35.
Simply add a 120K resistor and a bright LED:

When you push the backlight switch, the light stays on.
When radio is turned off, the light goes off-then push light switch and backlight will stay on for 15 seconds or so.
Thanks for sharing this simple mod, Rolf!
