Thomas- Beautiful build, so naturally this sent me down a rabbit hole to search out appropriate output transformers. An entertaining morning.

Let me know if you find anything

Also seriously considering building one of these.

Nate- I ordered this:

tca, interesting this little monster!

What is the project?

tca · « **Reply #546 on:** July 02, 2015, 05:39:35 AM »

^ Pretty basic, a 1W class A mosfet power amp, with bias control and lineout with vol.

nice, looks very etchable too..

tca · « **Reply #548 on:** July 02, 2015, 05:57:33 AM »

>nice, looks very etchable too..

... and hot, it has a resistor load which dissipates about 10W in heat + 3W of heat of the mosfet. That's why it looks like a monster.

you built a radiator..

or you can warm soup on it too...

I'd like to read a report of this project.

Can you tell us how it is comparing to the Punch Amp? It sounds clean? It is noisy? It supports 8 ohm speaker? Eq is ok?

Don't call me "inquisitive".

Thank you a lot!

Sounds much better, overdrives nicely with a booster in front of it. Sounds clean with good compression, high output impedance, can drive 8/16Ohms cabs.

Cheers.

Not directly by me but I am affiliated with a company that makes these and helped with building this particular one

A bit rough and ready compared to others on this thread. However, it works and I'm happy with it. This is my 'Lamington' 15w build housed in modified Ikea.

tca · « **Reply #554 on:** July 03, 2015, 09:35:36 AM »

Buildtestrepeat: What are that corner protections? Similar to the ones used by midwayfair in his amplifier.

Modified Ikea box?

Looks great!

diydave · « **Reply #555 on:** July 03, 2015, 10:34:16 AM »

Nice build.
Love the way the mesh is used.

The corners are very similar if not the same as those in midwayfair's post. I got them at a hardware store. The box is from a small storage unit called 'Trofast'. I just used the top and bottom of the unit and cut down the sides to the right height. A small amount of routing and a few drill holes and it was done. I can unscrew the box and make it flat pack again

. The mesh is cut from the bottom of a storage tray and painted gold, then just screwed on inside the front panels.

Cheers for the likes.

Hello DIYers All,

I came to compliment that thread of exhaustive nice amp and cabs releases all around...

Here is my last creation, designed and built from scratch, and just finished these days, a 50's-60's styled guitar amplifier : The COMET .

If you don't like that vintage style, it would be better for you to skip... But if (like me) you like it, then enjoy

!

Note that it is a personal, non-commercial production : I have nothing to sell and sell nothing... That must be said to avoid any misundertanding about the aims of my releases.

Let's go :

At the start, plywood and aluminum :

The UTAH AlNiCo restored/reconed 10" speaker form 1957 :

The faceplate and logo, vectorial drawn and laser etched :

The Tolex covering color choice (Ivory White / Surf Green) and grillcloth pattern (Fender BlackFace RI white-silver-black) :

Assembling the cab (nailed-screwed-Vinyl glued, angle-braced) and presenting chassis :

Presenting loudspeaker ans chassis :

Covering and Grillcloth-ing :

Chassis preparation, drilling and surface "bouchonnage" :

Chassis assembly and wiring :

The finished amplifier :

A+!

Stunning work Bruno, absolutely gorgeous! Thanks for sharing.

How many hours do you think you need to finish such a project?
Thanks,
dave

The cool factor meter just broke

Thanks for sharing
