Not so. Tubes and associated parts are not hard to find in Italy and the EU

Ok, you've wired your tube amp like said on the intructions. But when making them, the producer lost a step in the process. You end up with an anode connection on a pot. You put 100$ of tubes in, you power it up, you fry all the tubes and probably kill yourself. Bad idea.

Bit too much hyperbole there.
For any thinking individual with a passion to build something, and the patience to learn how it's done, it won't be a problem. Awareness of potential dangers and patience are the most important aspects of learning something new, so armed with these a novice should have no difficulty. And people around here will usually answer any 'help me' posts if someone is unsure.

Heila Brett! Thanks for the links: I really didn't know them. Prices are good!

I agree totally with you about starting learning building a tube amp. These are my beliefs too.

At this point, I can only suggest for www.ax84.com

If the guy shows he's alive and tell us what do he think about tubes...

We're open everyday for answers!

Giaime, "poo poo" is an American slang phrase that means to dismiss or to speak negatively about.

The boss poo poo-ed my suggestion. The boss spoke negatively about my suggestion.

I told my friends I didn't want to fly because a falling space ship might crash into the plane and we should go by boat. My friends poo poo-ed my concern.

poo poo is also children slang for poop or feces. I think the terms are related. SOmeone poo pooing my idea is essentially calling it poop.

(Sorry, I originally had a bad word there and the system censored me, so I changed it)

I think a simple solid state amp may be a better choice for an absolute novice, I just didn't want to dismiss tubes without discussion. Building something requires more than circuit knowledge, there is also just the part about using tools, handling materials, sourcing parts and so on. A kit reduces a lot of the tangential stuff. But is someone has already spent some time on the workbench, he may be readu for something a little more complex.

Absolutely agreeing with you. And thanks for the "slang" lesson! These are things that our english teacher didn't tell us...

I have but one tip for you.
Look at the most famed and acclaimed tube amps.

Less is more.......

I built a few amps arround the LM3886 (2 guitar and one Bass amp) and they sound really quite good....You could simply buy a Lm3886 chip amp kit and throw a good Pedal in front of it or even a simple tube preamp....My Main LM3886 amp has a 3 band active tone controll with 2 seperate OD stages that can be enabled or disabled...It sounds very good and is quite loud.....

Cheers

Do you have a layout or schematic for this I can look at? I purchased the LM3886 boards from chipamp.com to build a guitar amp but most of the stuff I can find about chipamp boards is all related to home stereo stuff.

Any info. greatly appreciated.

Hey , Um ... sorry , My computer crashed about 6 months ago and I lost most of my layouts and schematics .... I have a layout for a Tube guitar preamp that runs off of 12V , it has lots of features but it is a pretty complicated project and there is a lot of off board wireing and it is a difficult PCB to etch at home,

I am useing it to build a 2 channel stereo Guitar amp right now and throwing a 5 band EQ after it into a Stereo TDA7293 Kit with speaker protection , it is my most complex project to date , it has 18 Knobs and 11 switches and takes up a 6U case ....

I can send you the PCB layout , a wireing diagram , and stuffing guide , but I can"t post it because it is a copy of a comercially available kit and I don"t want to get in trouble for posting copyriteted artwork ... you might be better off just buying a kit somewere or just throwing a pedal in front of the chip amp ....


Cheers

Hi,
I'm trying to figure that out myself , planning to build one this summer. This site I found is really helpful, it has instructions for how to build various tube amps with different tones, I think it has some theory stuff too. Check it out
