I can't think of anything that could cause a mechanical timer to kill a CFL.
It's nothing more than a motor-driven toggle switch, after all.

There's a website somewhere (I think the one that describes how to turn a
discarded CFL into a QRP transmitter) that shows the insides of a number of
different models.

Maybe you can send your photo there.

Personally, I don't think it's fair to condemn all CFLs.  We live in a brave
new world with zero quality controls, 100% cheap imports from the other end
of the world (yes, driven partly by Walmart, others followed suit to remain
competitive), and no accountability.  So I think we are going to see huge
variations in product quality.

What made yours go bad MIGHT be if it was designed by some guy with little
experience, re-designed by bean-counters to cut the cost in half,
manufactured by some no-name company using cheap labor trying to make a
quick buck in today's world.  I don't recognize most of the brands on the
store shelves; they weren't here 5 years ago and may be gone 5 years from

Maybe I got lucky and bought the right brand(s), I don't know.  My
experiences with CFLs are far better than yours ... so far at least.  I
thought I had one go bad on me last week (first one in 5+ years) ... but it
turns out it had just gotten a little unscrewed (a few too many times
slamming the door).
