In case anyone can help, I need a copy of the March 2004 issue of Elektor
Electronics magazine (Nr 330), to complete a break in a library sequence.

I will of course pay for the copy plus postage.

Please help if you can.

Elektor used to be my favourite as a 'yoot' doing electronics as a hobby
in the 1980s when I got fed up with Hobby Electronics and ETI.

I have some of their 30x circuits books somewhere - they always came up
with a circuit idea when I needed something.

However I actually found a use for one of them a few weeks ago, when the
starter in the fluorescent lamp in my garage failed and I didn't have a
replacement.

I remembered that there was a small circuit for an starter using a thyristor
(which I have dozens of) so after a long search the appropriate magazine was
found and the circuit hastily constructed on a piece of Veroboard, worked a
treat and the tube now springs into life instantly!

come on at all.

Hi!

To add to your anguish, I just looked at the only two copies of Elektor
I have.

They are Febuary and April 2004 :-(

Yours, Mark.

Sure Elektor is still going! Just bought a copy recently when I was in
Germany. It is every bit as good as it always was.

Actually I resuscribed again this year, I still have the first issues from
1972 or so, but I never opened them again, they are stored somewhere in the
basement. If some offspring continues my way, he could one day find these
mags and reread them. Well, my eldest son(29) is just doing his PhD in EE.
You are right, lots of interesting things inside, much better than Circuit
Cellar, which is defined to PICs and alike.

It will obviously depend on its use. If you're using them for an important
application, then it certainly makes sense to replace them regularly -
although how often will depend on the amount of use, the type of tube and
the type of ballast. Modern high frequency types are far kinder to the
tube than switchstart ones, as well as more efficient.

If all it's doing is lighting the stationary cupboard, then as you say
most wait until it fails. Which can be a very long time.

Back in the '70s I managed apts for a guy who worked at
McDonnell-Douglas, in Long Beach, CA. He would go to the surplus sales
and buy a whole carton of 4' or 8' fluo tubes. The maintenance guys
would sweep thru the bldgs with ladders or cherry pickers and replace
every tube in every fixture, because since they were union and labor
cost so much, it was cheaper to just replace everything at one time, and
of course it also gave brighter light.

He would bring a carton of used tubes to the apts and most of them would
be just fine, since they had been installed just a year earlier as
replacements.
I don't know if they still do this, but it makes sound economic sense,
obviously.

That must be a universal practice, as several years ago an electrician
friend gave me about a dozen perfectly good 4' tubes which he had acquired
for the same reason, i.e. companies blanket replacing them at set intervals,
irrespective of whether it was needed or not.

I ever worked in an airforce hangar. Changing a tube was a hell of a job
that interfered with the ongoing maintenance tasks. So if the percentage of
failing lamps raised above 2% (if I remember well) they planned a day to
replace all tubes at once.

BTW, where can I find the starting circuit mentioned in the original post?
