Default Looking for a tube amp

Hello everyone!

I'm about to start a project and my "goal" is to build a tube amp.
I prefer a kit, only the tube amps.

I've found some tube amps witch is quite interesting from this site:
Kits - HiFi Tube Amp

Do you know witch one of these is mest for me??
It have to support 8 ohms speakers.

Or is there anothere site that is better?

I don't want it to be too expensive. Lets say about 400 dollar is maximum. BUT if you can found a tube amp that is really good for a little more its okay, you got it?

I live in sweden by the way.

EDIT: I don't know anything about tube amps or anything simmilar to it.

Sounds like a great idea.
First you asked me about "el84 or 6L6, pushpull", are they diffrerent kinds of tubes? And what is pushpull? Is sounds, to me, how the tubes are paired togheter or something like it.

Here is a good read on tubes and how they differ and each of them work.

Thank you!

I have been reading and I'm afraid that I am no longer interesting in building a complete kit. I want to pick/choose all parts myself and build it

I can ask you about this. Which part contains in a tube amp?

First I would think you'll be looking at the sort of Output Power you want from your new creation....

This will dictate to a certain extent What Kit you end up with, whether the design is -Push -Pull, or 'Single-Ended'

Each has advantages/disadvantages over the other...

So--IF say you're looking at around 20W per channel amp, probably you would be looking for a Push-Pull amp using summit like EL34 or 6L6 in Triode, or maybe with a little less power, EL84 in Pentode...

If you're only needing a couple of watts then a 'Single-Ended' amp, using Triode-wired output pentodes or if you have a little extra to spare, 2A3 or 300B triode output valves instead

A LOT depends on personal taste and the needs you have of the amp. This will direct you to what you'll end up with....

Worth looking at 'Tubelab' kits he's a member here and has a little section for the builders of his kits....
