I was wondering, would it be possible to build a tube amp that used 100 watt incandescent light bulbs as power tubes? How would it sound? Has it been done?

I mean, if you think about it, 4 incandescent soft white bulbs that are 100 watts would be putting out 400 watts of tube power. That would be powerful as fuck. Can any techs here confirm this?

Or is just a stupid as shit question?

Tubes and lightbulbs are 2 very different things, they both light up when they have current running through them but that's about it.

lol
There's a good chance that what I've written above is useless and if you take any of the advice it's your own fault.

No, as light bulbs are made to create light using a filament, and valves are basically glass and wire transistors. Not at all the same thing.
It would be awesome though.

No. A power tube in an amp is essentially a poweramplifier. Weak signal goes in, comes out big. It has a cathode and an anode, and electrons flow through a vacuum. The glow is just a side effect, dont recall what its called.
A light bulb is......just a light bulb. It glows because its hot. Thats.....it. There is no flow of electrons through vacuum.


What the guy said about it being a glass and filament transistor, thats more or less right.

I think youre looking for this-



Its got about 20 something tubes in the poweramp.

Sure you can. You can also replace components on the circuit board for small pieces of candy as long as they're the right color.

Just make sure you get the clear ones because tubes are clear, so it should work just like tubes, right?

I dunno I think the tone would be a little too (wait for it) bright.

Tube amps sound ok with tubes but with lightbulbs they really (wait for it) shine.

Considering the weight difference, a tube amp running on lightbulbs would probably be very (wait for it) light.

forget 100 watters lets get some 500 watt halogen floods for the total br00talz. we can use some nightlite bulbs in the preamp.

A couple of these 1000 watters in the poweramp should do it.

Let's not get burned out on puns, now. There might be a filament of truth in this idea.
#28
Well this sounded like a great idea, so I took all the power tubes out of my mark IV, broke the bases off, and soldered them to 100W light bulbs. It sounded AMAZING!!

On a side note, anyone know where I can get a new mark IV on the cheap?

oh man nice work on the puns

serious answer, though: a lightbulb isn't a tube- you have a cathode, anode, etc. etc. all in a tube so it amplifies (or rectifies), whereas a lightbulb is basically just a filament which sends out light when it gets hot.

So yeah, it's not going to work.

Be sure to properly install the bulbs though, people often mess that up and the results can be (wait for it) shocking.

it's a light bulb, and I don't think it's a tube. However, for a light bulb, it is very good. Don't plug guitar into it; just use it as light bulb if it works

Actually, the advantage to using light bulbs is that you can buy the ones that last like five years so you don't have to worry about(wait for it) blackouts.

Maybe if you go to star wars land you can get a lightsaber and stick it in the amp so you can have more(wait for it) cutting edge distortion.
