Is there a starter? - 35p each, I'd try this first

Thought the same, done that.

So you've got switchstart fittings. Then it's wrong
starters,
bad tubes or bad contacts. The capacitor can't cause this.

Corse it can.

And is in fact by far the most likely problem when the tubes
arent connected in series after the things he has tried
already.
The capacitor will be across mains in.

Yes.

Good, we have got that far.

Can you explain, assuming the supply impedance is in the order
of a
fraction of an ohm, why a capacitor can cause the
perturbations in
voltage supply to cause a substantial flicker?

You havent established that it is causing perturbations in the
voltage supply. And it can obviously do that by not being a
viable cap anymore anyway.

Is that an admission that its not the capacitor?

Nope. If the tubes arent in series, that is by far
the most likely cause of the problem given
what he has tried that has made no difference.

Or are you thinking of some other capacitor characteristic that
might
cause this flicker,

Failure mode of electros, yep.

Electros? Is this a new component technology?

Certainly electrolytic capacitors are rarely used across AC
mains, so
it must be some other capacitor technology.

if so do tell.

Most obviously if its got a significant partial short
now, as electros sometimes do when they have failed.
That could easily see the tubes no longer getting full
mains voltage anymore, and so flicker now.

Are you now suggesting this partial short will be causing
perturbations on mains voltage?

Nope, reduced mains voltage across the tubes.

And I didnt say WILL BE, I said IF.

Previously you said we haven't established that such a "partial
short"
would cause "perturbations in the voltage supply".

Everyone can see themselves that I said nothing of the sort
previously.

You really ought to make your mind up.

You never could bull**** your way out of a wet paper bag.

Is that your answer to a question you have failed to answer?

Everyone can see for themselves that the question was
answered, you pathetic excuse for a lying bull**** artist.

You said it could be the cap. I have asked how:
"Can you explain, assuming the supply impedance is in the order of a
fraction of an ohm, why a capacitor can cause the perturbations in
voltage supply to cause a substantial flicker?"

Everyone can see for themselves that the question was
answered, you pathetic excuse for a lying bull**** artist.

You are incapable of providing an answer as to how a faulty
capacitor
can cause flicker.

Everyone can see for themselves that you are lying
thru your ****ing teeth, as you always so when you
have got done like a ****ing dinner, as you always
are, you pathetic excuse for a lying bull**** artist.

Are you now denying your reply of "Corse it can."

to "So you've got switchstart fittings. Then it's wrong starters, bad
tubes or bad contacts. The capacitor can't cause this."

Nope, the cap can cause what he is seeing.


Once again I ask you to explain how, given the low impedance of
supply, even lower since it will be for lighting.


You have no idea what the impedance of
the supply is with that PARTICULAR fluoro.


Most supplies are a very low impedance,


Most is irrelevant with faults.

there is also the 3% limit of voltage drop for a lighting circuit.


Also irrelevant with FAULTS.

Is this your way of back-pedalling

No back pedalling at all.

Clearly you're just unable to explain your assetion.


It isnt an assertion, its a fact and when someone like
Adam has seen it, doesnt need any explanation either.


You mean you can't explain it?


Everyone can see for themselves that I did,
you pathetic excuse for a lying bull**** artist.

And rubbed your stupid nose in the FACT that there is
no need for any explanation when its so trivial to remove
the cap and see if its what is causing the problem after
the more obvious possibilitys have been tried first.

You came up with an assertion, not a fact.


Its is a fact that a bad cap can produce what he is seeing.

Just because Adam has 'seen it' it must be so?


Yep, when he has seen a bad cap do that, that is precisely what it is.

Do you see him endorsing your assertion with an explanation?


Dont need any explanation, just observe
that removing the cap fixes the problem.

And the explanation for why removing the
cap fixes the problem is so ****ing obvious to
anyone with even half a ****ing clue anyway.

All it needs is to rub your stupid pig ignorant nose in
the FACT that a bad cap can produce that result and
given its so completely trivial to prove if the cap is
the problem in this particular case after the more
likely possibilitys have already been tried, only a
terminal ****wit such as yourself wouldnt try it without
the cap and would demand an explanation first.


If its trivial to prove an "electro" can cause flicker, do tell.


Just did. Remove the cap, it doesnt flicker anymore, ****wit.

by calling me a "lying bull**** artist"?

Thats not calling you anything, its a statement
of fact as everyone can see for themselves.


You start calling people names when your knowledge is lacking or
you've lost the case.


I call lying bull**** artists lying bull**** artist when they
lie thru their ****ing teeth as we can all see you doing.


I don't see how asking you to explain your assertion is a lie?


I never said that THAT was a lie, you lying bull**** artist.

You lie was about what you claimed I had said, you lying bull**** artist.

Until you can explain how a relatively small capacitor can cause
supply anomalies to cause flicker by an "electro" your statement of
fact"


Its a fact that Adam has seen a bad cap produce that, ****wit.


I don't see him explaining how a faulty 'electro' can cause flicker, do
you?


Doesnt need to when removing it stops the flicker, ****wit.

reams of your **** any 2 year old could leave for dead flushed where it
belongs

And Adam has said that it could be the cap.

If Adam said "jump of a cliff" would you feel obliged?

You never ever could bull**** your way out of a wet paper bag.

You'll have to pardon us if we decided that Adam might just
have more of a ****ing clue what a failed cap can produce
than some gutless pathetic excuse for a lying bull**** artist.

We all know you call people names

Thats not calling anyone names, thats a statement of fact.

when you've lost the argument.

Havent lost any argument, you pathetic excuse for a lying bull****
artist.


You haven't won an argument


Dont need to. If the OP still has the problem,
its obviously worth trying without the cap and
costs very little more of its time to try that.


reams of your **** any 2 year old could leave for dead flushed where it
belongs

but have lost it until you can explain how how a relatively small
capacitor can cause supply anomalies to cause flicker by an "electro"?


Even sillier than you usually manage. Dont need any explanation,
JUST see the removal of the cap fix the problem.


reams of your **** any 2 year old could leave for dead flushed where it
belongs

And even a terminal ****wit such as yourself should be
able to work out how to check if the cap is the problem
if someone was actually stupid enough to lend you a
seeing eye dog and a white cane.

And he still hasn't come back with an explanation.

Presumably he's noticed that you are a lying bull****
artist and that the best approach is to just ignore you.


I suspect Adam isn't sure


He doesnt operate like that.


reams of your **** any 2 year old could leave for dead flushed where it
belongs

and is waiting for your explanation of how a relatively small
capacitor can cause supply anomalies to cause flicker by an "electro".


He actually said that he has seen a bad cap do that.


There might be situations where a bad cap could, but not in this,


How odd that Adam has seen it.

reams of your **** any 2 year old could leave for dead flushed where it
belongs
