Ok, so heres how it is. At school in recording class we have these terrible little tube amps that have verry little overdrive/distortion. I dont know what there called, but we also have some Behringer preamps. So would i be able to plug my guitar into the preamp, and then plug the preamp into the input on the amp to get it more overdriven? IS this possible without a big explosion? any other things i could do would be greatly appreciated.
Thanks

I heard there is uranium gas in the tubes. So you could easily make a little nuclear blast. If i were you, i wouldn't want to start the World War III.

They're only joking. OFCOURSE you can plug it in, it's safe.

It won't make a big explosion, just a kind of popping noise followed by the smell of burning and ultimately silence.

Nope, not kidding

Long before vacuum tubes were discovered as electronic devices, the blue glow of "not so clean" vacuum was discovered automatically. All you need is not so good vacuum, with a very tiny fraction of air, and the tube is gets conducting at high voltage, emitting bright pink light. These were the "Geisler" tubes, and soon these were used in all kind of variations. The discoverer of the so called Geissler effect, had no idea what caused it. You must imagine the days where electricity was just discovered, and street lamps had candles in it. The use of those tubes was only for impressing people with the magic of electricity . Later they made medical lamps of it. Though it didn't cure any disease at all, even real medical doctors were offering fake treatments with it. (Sounds familiar somehow)
The Geissler tube is made of a glass cylinder with an electrode at each end. They are vacuumed, but contain a very minor fraction of gas such as neon, argon, or air. Also conductive liquids or minerals can be used. When a high voltage is applied to the terminals, an electrical current flows through the tube. The effect that takes place is the following. Assume an electron gets freed from a gas molecule. Now the ion (+) goes to the negative electrode, and the electron (-) to the positive electrode. Since the weight of one ion is very little, it will accelerate very much and will hit the electrode with a lot of energy. On the way to the electrode it will hit on other gas molecules, and will free some electrons from those as well. The recombining ions + electrons will emit a frequency by the formula F = E / h. Where E = the recombining energy, which is a constant of the used gas. The factor H is also constant, so the frequency (spectral line) is always the same. Some gasses emit a frequency in the visible light range. Some can be in the invisible range. The light will be a characteristic of the material contained within the tube and will be composed of one or more narrow spectral lines.

I have no intention of trying this mostly because I don't have a reason to, but wouldn't plugging a preamp into the front-end of a guitar amp do the same thing as an overdrive or boost pedal?

It may not sound good but since the signal is going to come out of the preamp at a low level it shouldn't do any more damage than a boost pedal or something similar would it? Now plugging the output of a power amp into another amp will definitely blow something up but a preamp I would think should be safe.

Yes, though it's a line level signal not an instrument level signal like your guitars pickups going into the front of an amp.

The standard way that this is done is via a power amp via the power amp's inputs, an effects loop return or poweramp in jack on a combo.

2) how does that explain uranium in a tube? 0_o

3) i can copypasta too

Quote by internet
The vacuum inside the envelope must be as perfect, or "hard", as possible. Any gas atoms remaining might be ionized at operating voltages, and will conduct electricity between the elements in an uncontrolled manner. This can lead to erratic operation or even catastrophic destruction of the tube and associated circuitry. Unabsorbed free air sometimes ionizes and becomes visible as a pink-purple glow discharge between the tube elements.
To prevent any remaining gases from remaining in a free state in the tube, modern tubes are constructed with "getters", which are usually small, circular troughs filled with metals that oxidize quickly, with barium being the most common. While the tube envelope is being evacuated, the internal parts except the getter are heated by RF induction heating to extract any remaining gases from the metal. The tube is then sealed and the getter is heated to a high temperature, again by radio frequency induction heating. This causes the material to evaporate, absorbing/reacting with any residual gases and usually leaving a silver-colored metallic deposit on the inside of the envelope of the tube. The getter continues to absorb any gas molecules that leak into the tube during its working life. If a tube develops a crack in the envelope, this deposit turns a white color when it reacts with atmospheric oxygen. Large transmitting and specialized tubes often use more exotic getter materials, such as zirconium. Early gettered tubes used phosphorus based getters and these tubes are easily identifiable, as the phosphorus leaves a characteristic orange or rainbow deposit on the glass. The use of phosphorus was short-lived and was quickly replaced by the superior barium getters. Unlike the barium getters, the phosphorus did not absorb any further gases once it had fired.

Um ya, the info I posted was correct. I'm not interested in arguing the merits of correcting misinformation, that you or anyone else puts out there. I felt it needed to be done, since you come off as an expert/authority on the subject, and were wrong. Re: copy/pasting info: There is a reason researchers, engineers etc... have access to research material--because it's unneccessary to type a novel when trying to access info to get a point across.

Do not do it.

Really. I'd recommend against doing preamp into preamp into power amp.

If you have an fx in on the tube amps, then you can run the beringer (why? ) into the fx in.

Don't do it though.

TS: No, there is not uranium in tubes. I don't see how that came up, but no. As far as hooking up Guitar-->preamp-->amp... I wouldn't do it. That's running two preamps and a power amp, and would probably blow something. So don't do it.

first of all, just bring an effect pedal in, second, vacuum tube means theres NOTHING in it, and if there were uranium in it, youd die next to the amp while playing just from radiation, and there wouldnt nearly be enough for a nuclear explosion which would require enough uranium to be at lease critical mass which i think is 1 kg.

This thread has basically descended into spam anyway... so I'll add my little bit of disapproval in here too!

No. You wouldn't "die next to the amp," radiation is a slow poison, not an insta-kill (BOOM HEADSHOT) style.


To make my post even remotely helpful...

If the amp had an FX loop going guitar > amp > FX Send: Behringer > amp; should all be ok right...? At that point it's all line level once the second preamp comes into play.
