It's not clear what you're looking for.
On the one hand, it appears you're asking for a tube power amp schematic. This implies that the input will be line level.
On the other hand, perhaps you want an amp with a "guitar" input but without any EQ controls.

My first tube amp build was a Fender Champ 5C1.
Here's the schematic:

It's simple, it works, and all the components are easily obtained. I built mine in just two evening sessions, as I recall.
I built it as a head, and it was a very nice sound with a 12" speaker.

If you don't want your guitar's tone to be affected by the amp, your best bet is actually a highly linear solid state amplifier. Those are still always going to apply some colouration because nothing in life is free, but as far as taking an input signal and making it louder with the maximum accuracy possible, tubes suck at that.

Which is of course why people like the way they sound.

You're still confusing me. :scratch:

The Marshall head you linked to will only accept line input. You're sure that's what you want? That's about 20x the signal strength of what you're passive guitar pickups put out.

Also, that Marshall would probably fall under the category of "BIG" for most people. You said you wanted a "small" amp in the first post. Please define "small." If that Marshall head is "small," then I can't imagine what your "BIG" is. :lol:

So you want a Marshall amp? OK, pick an amp that fits your power needs, pull up the schematic, and if you're stumped on where the "power amp" input is, then we can help.
The schematic for the Marshall you linked to is available, if that's the amp you want. Follow bajaman's suggestion.

You obviously have never tried plugging your guitar into a hifi amp and speakers.

does anyone can help me??

Yes, save yourself a load of time and trouble and get a proper guitar amp with all the necessary filtering and colouration, guitar amps are not hifi for very good reasons.

This document is written in a strange language (sorry I write better portuguese than english), but I think all schematics and data are quite universal - google translator can help you too.

http://www.gamal.com.br/iall/iall-10.5-1.0.7-labnotes.pdf

This is an example of small power amp (10 watts). It is pretty tested. I (and some people in Brazil) had built some... But remember, I take no responsibility about the final results of your build!

Take care to high voltages the circuit involves!

In the event that you don't need your guitar's tone to be influenced by the amp, your most solid option is really an exceedingly direct strong state intensifier. Those are still continually going to apply some coloration since nothing in life is free, yet to the extent taking an info flag and making it more intense with the most extreme exactness potential, tubes suck at that.

He may use a ECL86 tube (or ECL82 ) which has a builtin triode ( which can serve as a preamp)
