In one of the threads last week - can't remember which now - I spoke of
working with some big power valves (tubes) in amplifiers that were used to
run a radio relay service around the town where I live. Someone asked if I
had any links to these foot-high beasts with nuts and bolts in, and I said I
would get the type number from my buddy who has still got a couple on a
shelf in his house. Well, turns out that he has kept them so nicely
polished, the numbers have rubbed off ! However, a bit of research has
turned up this

http://www.r-type.org/exhib/aaa0529.htm

complete with the perfect description of the self-same amps that we had
feeding audio out around the town. I remember the mercury vapour reccies
flashing away with the music, and the grid and anode meters. Also, the rack
of additional valves. I seem to remember that the drivers were KT66's or
maybe 88's, but I could be wrong there. The only thing that seemed at odds
with what I remember, is that I'm sure ours were running on a single phase
supply. Our office / workshop was located in a normal 'domestic' pair of
semi-detached houses, knocked through into each other, so it's unlikely that
there was a three phase supply in there. Prior to us moving to those
premises, the amps were located in the window of a small shop which served
as the 'HQ' building. I'm pretty sure that would also not have had a three
phase supply.

I remember also, the old boy who was the chief engineer for the whole
system, telling me that they were the same amps as were used in the Royal
Albert Hall for the inductive loop headphone system. Anyone else had
anything to do with these monster amps ? I wonder if there's still any doing
service anywhere as modulator racks on any remote little backwater AM
stations ... ? :)

Looks like a modulator for a big old xmitter.

We chatted about this a while back. I'm a power tube lover. I love the
smell of rarefied air around power supplies and tube anodes. I love
the fact that you're working with voltages/currents that could
instantly kill you. My favorite 'tube' has got to be the mercury
rectifier. I forget what island but one island had AC piped in and for
some reason built this giant MAR. I don't think this was the railway
substation for the Isle of Man although that one built in the 30's is
pretty awsome and still in use.

Ummm... that would be the ozone. If you make a habit of ozone
sniffing, you may want to check if you're exhibiting any symptoms:

When I worked in 2way radio in Smog Angeles, we would kill or
hospitalize at least one technician a year, usually due to high
voltage electrocution. My introduction to the statistics was holding
a grounded metal case microphone in one hand, while probing around
with a long screwdriver in the other hand. That last thing I recall,
before the lights went out, was a brilliant purple glow (caused by a
combination of parasitic oscillations and a gassy tube) in the final
output tube. I later repeated the same mistake several times before I
learned my lesson and purchased a better insulated screwdriver.

I haven't had any personal experience with mercury vapor rectifiers.
That may help explain why I'm still alive today.

I have an ozone generator + filter. In the right PPM it's beneficial
to kill airborne disease. Thanks to that thing I haven't suffered a
cold or flu as long as it's been running.

I clipped a wire in an operating voltage tripler with a pair of wire
cutters that had a barely visible nick in the insulation. I didn't
have a path completed except to the floor wearing regular street shoes
but received a fairly nasty burn and shock. I have been shocked into
near unconsciousness pulling the guts out of an old photographer's
flash supply. Couldn't get it out of the case so I grabbed two un
insulated hemostats and clamped on to two places at the same time
which unbeknown to me were the outputs of the banks of capacitors that
had retained a charge.

the MAR was used extensively in subways and subway cars back before
selenium and other SS rectifiers were available. If the power rails
were DC the MAR was in the loco. If not it was located at
substation(s) located at the main terminal and on the route.
MARs were sealed and what mercury was arced during rectification
collected on top the glass bulb then dripped back down into the pool
at the bottom and the process repeated.

I don't doubt there were on occasions mercury contanminations though.

The mercury vapour rectumfriers that were in the amps, are not quite the
same beasts as 'traditional' mercury arc types, although the rectification
physics is similar, I believe. The MVRs that were in the Philips amp racks
that I referred to, were just like ordinary sized and shaped tubes - KT66ish
sort of size, as I recall. I don't think that they were good for too much
current, but handled the anode voltage for those 212's just fine. I think
that the mercury vapour discharge was self starting.

http://www.uli.de/tubes/866a.htm

The ones I always associate with being true MARs, have a big pool of mercury
in the bottom, and starter electrodes that dip in it, and arc the vapour out
of the mercury to precipitate the main ionisation discharge to the anodes.
When these lovely beasts are running, that ignitor electrode (is that the
right name for it ? - been a long time since college ) dances about on the
top of the mercury pool. Very pretty. The whole bizarre-shaped envelope of
the device lights up purple. MARs are good for both high voltage and high
current I think.

My first experience of them was at my local cinema when I was a kid. I had a
little Saturday morning job 'helping' (!) in the booth. That involved
sweeping up and rewinding reels and so on. Both main machines and the big
slide projector used for static adverts, employed carbon arc lamp houses,
and the DC for them, was fed from a pair of MARs in a big cabinet in the
corner of the booth. A bit like an office double door steel cabinet. They
fascinated me from the time I first set eyes on them, and I'm sure that
they, along with the amplifiers I have been discussing, which I first saw in
the window of the small shop where they were originally housed, set me on
the path to a career in electronics,

Aye, back in my youth - I grew up on a fairground - I was fascinated by
the big mercury rectifiers on some of the rides. I remember the old
French guy who had the dodgems was having trouble with fuses blowing, he
'cured' the problem using the showmans method - a six inch nail. The
eventual result was that the glass of the rectifier cracked around one
of the connections! There was lovely fireworks display inside the bottle.

I've only seen them in video that I can recall. By the time my
interest in electronics sparked it was 1970 and all I had was the blue
gaseous glow of 6L6 tubes in Fender amps to marvel at :)

I did however construct a tube rectified voltage tripler from a
schematic in a school textbook that put out close to 1kv no load.
The textbook was borrowed from a friend who went on to get a college
degree in electrical engineering. I have three friends who got those
degrees, I chose another path in life and now kick myself in the ass
for doing so. However one of these friends got me my first job in the
electronics field back in late 70s and I quickly surpassed his
technical abilities because of my passion.

to kill airborne disease. Thanks to that thing I haven't suffered a
cold or flu as long as it's been running.
And now just wait for lung cancer to hit you.

Ah ok. So ozone causes lung cancer?
Ozon is one of the most aggressive gases there is.

If any of that reaches your dna inside your lungs, bad things happen.
It is no accident that bugs are killed by ozon.
And damage is proportional to exposure.
The occasional thunderstorm wont harm you.
But the air fresheners going 24/7, will.

I don't think there's a cancer link quite yet. However, breathing
ozone causes some rather nasty pulmonary irritation:

There are also hints that it has secondary cardiovascular effects:

My mummy never told me it was dangerous breathing in all that ozone, after
playing with my electric train set for hours and filling the room with that
distinctive arcing and sparking smell.

Ah ! A subscriber to the dimethyl sulphide explanation then ... Well, that's
ok. They'll all kill you in the end. Just like anything you eat or drink or
do from the moment you wake up, to the moment you go to sleep again (and
probably whilst you're asleep as well ... ) d;~}

It is also responsible for preventing cosmic rays from burning us
alive.

If any of that reaches your dna inside your lungs, bad things happen.
Click to expand...
Any? Air is composed of 78 % Nitrogen and 11% Oxygen .05 ppm Ozone and
other trace elements of helium, hydrogen, argon and a few others.

It is no accident that bugs are killed by ozon.
Click to expand...
Yeah and it's no accident that those bugs killed by ozone are
microscopic.

And damage is proportional to exposure.
Click to expand...
I run my ion generator at 05 ppm. Millions of these air in use today
in healthcare facilities and hospitals.

The occasional thunderstorm wont harm you.

It will if you get struck by a lightning bolt.

But the air fresheners going 24/7, will.

I've been running mine for what, 15 years and don't seem to have any
brain or lung masses according to a chest and head angiogram of 2008
when a small PE was discovered in my R lung. I know the dangers, have
consulted my family physician that I use a purifier and was given a
PPM by him not to exceed. Anywhere you have an arc you have ozone.
I don't see any bans on arc sources from the FDA.

I do however appreciate your concern. But I am well aware of the
concerns.

I guess not. Next time I'm seaside in a costal region known for
electrical storms I'll bring my ozone detector and a respirator with
an ozone filter..

Ok the moral to the story is live fast and die young :)
Or sit on your arse and worry about every little fucking thing.
Walk around with a gas mask on inside a Hazmat suit.

Or like I do, drink coffee in the morning, have a cigarette, go for a
ride on my Harley without a helmet and get sunburned. I do put a 60spf
sun block on my nose though, easy to get squamous cell carcinoma
there.
