Howdy,

What type of meter would I use if I pulled the strap to observe
heater current while a tube was under test? This is AC current.

Hello Glowplug:

You would place an AC Ammeter in series with the filament to
measure AC amperes. The meter type must be one that allows
for AC current readings.

Now, for the amperage capacity of the meter, I don't find a 539B tube
data, so you must know the current draw of the filament before you
connect any AC ammeter, else risk blowing a fuse or ruining the meter.

A 10 ampere fused AC ammeter might be a good 'blind' start. If the
fuse goes, you will require a more specialized AC ammeter
that can handle filament currents above 10 amperes.

What kind of valve (tube) is a 539B? I don't find this in the
Duncans Amps database.

** The "539B" is a Hickok tube tester.


Don't you just love ambiguous headings ??

Heh heh... had me going too. I was looking to see
what sort of tube a 539 might be...

In any event be careful that the ammeter itself doesn't
drop much voltage thru it. Also you'd want to know what the
voltage applied to the heater actually is. But heaters
are fairly forgiving.

** Try to get a nice "moving iron" meter with a large scale - 0 to 3 or
5 amps

A "moving iron" meter reads AC (amps rms, 50/60 Hz) and DC equally
ell - magic.

Phil,

The "moving iron" you refer to is normally called an "Iron Vane".


** No Mr Smartarse - "moving iron" is the common and trade name.


You are correct that this is an AC meter.


** No again, it is a AC/DC type - maybe just like you.


It should be said that this is the motor
type that moves the needle to a certain position.


** Noooooo fooooling ?????


Other types are D'Arsovol
( which is the most popular) and electrostatic (usually used for high
voltage) Iron Vanes, because of their universal appeal and age, are
getting
rarer than hen's teeth to find.

A Google search of "Iron Vane Meter" quickly produced many hits,
so I suppose they (Google) are not aware of Phil's definition.

For example, see

But Sander, didn't you realise our Moppet Valve is a bleedin
expert on Australian politics?

The Oz election, unlike the Spanish election, shows that
most Oz folks couldn't give a ****e about any social or foreign affairs
issues and as long as interest rates don't rise on the record high
mortgages
on houses, and people are employed, with full bellies, **** all else
matters.

The opposition leader we have has only been at the job a few months, and
he is yet to
mature into a force especially if Lil Johnny Brown Nose starts making
mistakes
that all leaders make before they eventually leave politics.
Lil JBN knows about as much about human rights as LV,
but he sure does know about keeping a country's accounts in the black,
and that's the greater thing in voters eyes here.

It would have been some what different had we had say 100 lives lost
in our infinitessimally small contribution to the
stealing of oil from Iraq.

Maybe the Oz soldiers in far away places know how to keep out of trouble
better than the
yanks!

Maybe oil prices will soar, interest rates will rise despite Johnny,
and unemployment may creep up, and Johhny will be stuffed.
Its happened before quite a bit.....

About 7% voted for the Greens, which is an enchoraging sign, at least
a few people are concerned about the way the rest of Oz trashes our
environment.

Dear Pat - please dont start on Aus politics - it's every bit as
stultifyingly boring as NZ politics (just bigger).The electronics groups
are already infested with US politics much to their detriment. There
must be other more appropriate groups to go save/run the world.

I small drop of Oz politics won't make your brain fall out of your head.
LV is wrong about everyone being sad about the election.

The problem with groups is that the people partaking are human.
They focus in on one group, and get to know a few dudes,
and they like to discuss OT with those dudes, not ppl who
they don't know, ain't used to, and don't like arguing with
on the groups where politics is the main topic, and where OT
things about electronics and cars and pop stars ain't right to mention.
God, what a dull world it'd be if we always only ever
stayed on topic!

I will agree to disagree with you about the "worm farmers",
but you ought to see the mess the Murray river has become,
and in 200 years, I doubt Oz will be as able as it is now to
produce all its own food and export to elsewhere.
The Styx valley in Tasmania where the tallest eucalypts grow is being logged
mercilessly
for bloomin wood chips for japan. Maybe you're real happy to see such
ancient
natural wonders flattened, but I say our country is wealthy enough to
put asside the plundering of such places, on which the tourist industry
depends.

Maybe you like the sight of bulldozers rolling across every square inch
of countryside and destroying all, but I don't.

I'd rather be primarily concerned about my triodes,
but sometimes I look out the window, and I don't always like what I see.

And we had the hottest ever recorded october springtime temperature
yesterday.
Its queer, the Greens blame the T rise on the Red Necks, who know sfa about
the
greenhouse effect.

Imho, the world needs a few worm farmers to point out the excesses
of the loony right.
