It's not that they disrupt "the Magnetic Field."

(I assume you mean the Earth's magnetic field.) It's that they
create a very intense one of their own when detonated. "EMP"
is what it's called - "Electro-Magnetic Pulse."

they explode then all Computer's , Semiconductors and transistors will be
usesless.

Only in a limited area around the nuclear detonation.

There is some conjecture that a bomb tweaked for very high
EMP output could be detonated in orbit, producing a pulse intense
enough to destroy or cripple SS electronic devices over a large
portion of a continent. No way to test this without actually detonating
one, though.

Here are some thoughts.
1.) Since Semiconductors will be destroyed if there is to much radiation
/ or magnetic field will the Goverment go back to making Tubes and Tube
devices in order for our military to function.

Probably not.

However - there are redundant military comm systems in place to this
day which are tube-based, with battery backup or local power generation
capability. Military SS electronics, at least the mission critical systems,

are rad-hard (radiation hardened) as a matter of routine nowadays.
Consumer electronics will bite the dust in a matter of microseconds,
however. Everything from your phone to your car (unless it's an old
clunker with no SS ignition parts) will just stop working.

Some Tubes are too bulky
but if a whole new line of Nuvistor Tubes were to be designed we might
be able to survive more in a war or in a terrorist society. ???

It would be more likely that old stocks would be found...

or guys like me would be ordered to sell or give our NOS
(and new) stocks to the DOD if they needed them for
something. I don't know why they would, because tubes
themselves are useless unless there is equipment which
is designed to use them. Since production facilities
for SS devices are plentiful, more would be made.
Bootstrapping production would be difficult, but would
doubltless be accomplished using "seed" devices
which survived the EMP strikes - "accidental" Faraday
cages will exist, not every IC will fry. And I'm sure there
are a *****load* of spares socked away in rad-hard
hidey-holes.

2.) Military Aircraft need computers to help fly them. Would it be
possible to build a Nuvsistor type computer system to be used in planes
incase of a war . ????

Do you know anything about the systems in a modern jet fighter?

Enough tubes to duplicate the onboard electronics for an F-16
would probably weigh more than the plane!

3.) IF the Goverment wanted to go back to making tubes again - Does RCA,
Sylvania, GE have the old Tube Tools to make these tubes again ???.

Nope. All gone, or nearly so. Making tubes is a third-world enterprise
now.

Tubes today occupy a position exactly analagous to steam power.
Steam was once the primary motive force for all enterprise;
now, it's relegated to hobbyists and huge industrial processes
like electrical power generation or heating skyscrapers.
The large middle between those two extremes has been
completely filled by electricity for stationary power needs, and
petroleum engines for mobile applications. Tubes are now used
by guitar players and audiophiles, and in multi-thousand-watt
RF amplifiers/transmitters. Everything in the middle is transistorized.

4.) If say RCA, Sylvania, GE have lost the designs and tools to make
tubes again do you think that the millitary may ask the public say they
were to buy our left over tubes to dysect and use as a blueprint to

???

See above.

I would be a rich man. i have alot of tubes still....hahaha...
I think is an idea that the US Goverment should think about !!!. What
do you all think about this ???.

Not likely.

As far as I know, you can't detonate a nuke without a tube in
the firing circuitry somewhere. Klystron? Something like
that.

I do know this, however - I have a Hammond organ (B-3)
and two model 122 Leslies. If an EMP knocked out all
the consumer gear, I'd still be able to jam. I would,
however, have to jury-rig a tube rectifier system for the
Leslies, since they have SS diodes in the HV supply.

But I have *lots* of tubes. Jamming would probably be
the least of my worries, though.

I have plenty of guns and ammo, too. See ya at the
Safeway. ;-)

Russian (errrhh, Soviet) military aircraft were using a lot of tubes into

You'd probably need a generator too since an EMP event big enough to "knock
out all consumer gear" would also be big enough to take out major portions
of the power distribution grid over large areas. We saw how fragile the
grid was (and probably still is) about a year ago.

As you note, jammin on the Hammond would probably be low on the list of
priorities.

A curiosity in my collection: some JG-5751s by General Electric,
packed in May 1963. On the boxes are printed a little 3-leaf radiation
symbol, followed by the number 0.00001.

I'm guessing these tubes were hardened against gamma radiation, by
reducing the atmosphere in the bulb to an extra-small value indicated by
the number.

Any info, lore?

The vacuum in a normal tube would be a few orders of magnitude lower than
that, in torr. I don't know what gamma would do to a tube, however.
Probably just make it noisy, although you won't be hearing bonked subatomic
particles over the natural shot and thermal noise so, whatever.

Brian,

I have it under advisement by a person who designed such systems, that the
size and weight of such a device would prohibit it from flying at all. In
addition, the speed of tube device would be such that it would be better
if the pilot had a mechanical system. At least he would have a prayer of
flying the aircraft.

that a Soviet Pilot Defected from russia and the USA obtained the
Russian Plane and took it apart. What they found was this high tech
plane used Tube Types of Equipment to fly the plane and also Air Vacumn
tubes that would also control the plane - similar what is found in older
cars that use vacumn controls to control air conditioning heat and even
the windshield wipers. The Russians Knew that EMP's would kill their
Electronics so they Designed Equipment incase of a Nuclear War. To the

The plane this post is talking about was the Mig-25. It was a
"Mach-3" plane that had the US scared for a while until they got hold
of one. They found that it was an interceptor, not a fighter (heavy
and poor maneuverability). It could also not maintain its Mach-3
speed because it would over-stress its engines. It was mostly used
for reconnaissance (as was the US's Mach-3 plane, the SR-72). It was
not a fly-by-wire plane and the vacuum tubes were not used to control
the plane (at least not in the sense of fly-by-wire). They were used
as part of a very powerful radar that could penetrate jamming. Since
the plane was so heavy, it didn't matter as much that it used vacuum
tubes. The technology was described as "surprisingly capable" if I
remember correctly.

This is in contrast to something like the F16, which is a fly-by-wire
plane. It was designed to be deliberately unstable so that it would
be extremely maneuverable. The plane is so unstable that a human
pilot cannot fly it. A computer control system is necessary. The
human pilot activates a pressure-sensitive joystick on the side.
That's to make it easier to deal with high G forces. The pilot just
rests his hand on the armrest and manipulates the control joystick
instead of having a control stick in front of him like most planes.
The F16 is called the "electric jet" because of this fly-by-wire
feature. A computer made with vacuum tubes would be too heavy to
control this plane.

A little googling on the subject reveals that the speed was limited by
'controllability problems', though the engines would blow at March 3.2...

It came in a special radar version, as well as numerous other variants.


The technology was described as "surprisingly capable" if I
remember correctly.

I think it an example of excellent engineering (considering the crude
construction), describes as 'lacking refinement' but still capable of some
records:

(from http://www.spaceadventures.com/steps/edge)

Breaking Records:

In September 1967, a MiG-25 set a world speed record at 1,853.61 miles per
hour (2,982 kph). It stood for more than a decade, until broken by an
American SR-71 Blackbird in July 1976. It reached 2,016 mph (3,244 kph).
On July 25, 1973, a Ye-266, using the same airframe as the MiG-25 but
equipped with more powerful engines, set the world’s absolute altitude
record for a ground-launched air-breathing aircraft, reaching 118,867 ft.
(36,230 m). On August 31, 1977, the record was broken by a modified MiG-25
(E-266M) and taken to 123,524 ft. (37,650 m).


Pretty good for a handwelded steel-hulled jet with tubed avionics, eh? 8)
But it does seem it had its share of problems and limitations.


This is in contrast to something like the F16, which is a fly-by-wire
plane. It was designed to be deliberately unstable so that it would
be extremely maneuverable.

The MiG-25 is a high altitude interceptor, it wasn't build for
maneuverability. Seems like it was developed to counter the US B-70 bomber
(which was cancelled.) It does seem that NATO overrated the MiG-25 by a
large margin...

**No. It would simply buy it off the shelf. Gearing up to use tubes in
military equipment is (now) FAR too expensive.


Advanced technology improvements require large amounts of r&d money.

**Which is why you buy it from the people who have done all the work.

Back then, there was nothing on the shelf for ss hardening. We
developed it at a very high cost.

Just grab that plate in one hand, the chassis in the other,
and FEEL the power of tube audio!!!
(not literally, of course, just kidding. DON'T DO THAT!)

Hi RATs!

Military requirements change, both because the mission is not really very well
defined, beyond killing Those Bad Guys, and because new stuff is cool.

Some military applications use vacuum tubes, today!

Many do not.

Versus is a mental construct. It seems much more useful than it is

Happy Ears!
