need layout for low Wattage amp

[DaveWell]

Hi !
I whant to built a low wattage amp 1 to 3 watt.
I'M looking for schematic layout,
info on witch tube to use,(pre-amp and power section) i was thinking about a 12au7 and 6g6. ( or other suggestion)
An easy to built and modify amp , and tone that got ball'S !

If someone got good advise and idea ...

Best regards

Dave

Go over to the AX84 site and take a look at the Firefly and the 4-4-0 amps. Probably will find them in the archives or classic projects. They also have a 2 watt PP or SE power amp design that can be married to one of their preamps.

Why not just build a Champ? 5 watts isn't much louder than 1-3 watts.

If you really want something you can crank to distortion at home and not annoy neighbors, its probably under a half watt.

Hey thanks guy's !

I got this reply message from Kevin O'Connor

The low-watt output stage will be a tone bottle neck if it has a wimpy
OT or is made too small all the way around.

Otherwise, the essence of the tone you want comes from having a proper
preamp with sufficient tube count and gain to produce satisfying tube
tone. Most "low-watt" builders skimp on the preamp and are dissatisfied
with the outcome. Check out the Champ chapter of TUT3. Use one of the
two-tube preamps, such as the LPSP.

Have fun

Is someone know what LPSP Mean's ???

LPSP is the "London Power Standard Preamp" a very flexible design of his detailed in variation in most of the Ultimate Tone series volumes. It is a cascaded preamp design that uses the first two gain stages for clean and the second two stages for overdrive / distortion. Not too different than the "Dumble HRM", of course with a different "clean tone stack arraingement", component values and switching methodologies.

I will add, don't skimp on the output transformer size or speaker size and cab. I will also comment that at very low volumes diode bounding circuits can give convincing distortion results too.

Good, I got the TUT 1 , just hard for me to Layout it....

I just need 3 knobs and a switch

1 Volume
1 Tone
1 switch to Gain knob...

Maybe going with a simplify LPSP pre-amp (only gain stage for Overdrive)
A fender Champ layout,
And a 1k-1w resistor between Plate and G2 ( to lower the output)
or just 1K-1W to B+ to reduce power output

Any comment ???

Thanks !!!!!
