OOPS!

Don't ignore the burning smell just because you can't see smoke!
My burn in test time on the bench was short lived... I suspect the curve of the tuning assembly caused the copper at the end of the LED strip to short to the chassis... Scratch one test LED setup, and open all the doors and windows for a couple of hours... It still stinks in the workshop!
I didn't see it initially because the dial was on... when I finally clicked and lifted it, this is what I was greeted with:

So I spent some time and rebuilt it, bigger better stronger faster!
I might need to incorporate a dimmer function! The LED strip is now stuck to an intermediate thick insulating layer of high speed tape (not sure what else it might be known as - we used it in the air force on the leading edge of things like Iroquois rotor blades to protect them from impact). Heres a comparison.
No dial, lamp then LED:

There are no personal problems that can't be overcome with the liberal application of high explosives
