This Spud amp sounds very good and is priced very good.

I've built 3 of them, and use one as a backup amp now, but after several years of amp building and tweaking I'm still impressed at how this little amp sounds.

Cool, I'm not the only one who has backup amps! ;)

Any chance you could show some photos and share your experience with these spud kits. I'm sure the price and simplicity if the kit will interest a few.
Cheers

The pictures I have are from the older kit, the newer one is slightly larger and has 2 bends in the chassis. (Front and back) You can see a picture of a new finished one here.

The instructions come with over 100 high res photos, on a CD. They use a web interface with a menu system that's easy to navigate. Also the hawthorneaudio forums have lots of friendly folks that can help out, and Jerry is very responsive as well.

Here's a pic of my first Spud.

As a first time build, I enjoyed the simplicity of the amp, it's only 2 tubes and one gain stage, it doesn't get any easier unless you build a 1 tube preamp.

That looks like a very decent kit. I didn't read the description carefully, and am wondering if you provide the wood bits or do they come with the kit? Also, the one-piece metal top and back is a great idea-chassis are the most expensive part of these low-volume kits (I think) and the company is optimizing build quality with a cost efficient "platform" for the components. Thanks for sharing!

Can you tell us what the transformer model numbers are? I'm curious. It appears that there is one output trannie for both channels, or am I missing something?

The amp kit description indicates that the wooden sides are NOT included.

The Bottlehead Quickie preamp kit is like this too. I hate it when the chassis cost more that the rest of the amp.

The output transformers are open frame Edcor 8K to 8ohm units under the chassis, and there are 2 of them.
The PS transformer is a hammond 369AX.

Hi Everyone, Good starter project. Another entry to this field .... keep an eye out for the Oddwatt Audio Alpha. I'll say no more. I agree with the philosophy of good components and simplicity of design. My hat's off the the designer of the kit. There is a real need for entry level amps that can lure folks into tube audio. The amps IMHO need to be complete packages and have great (if not in huge quantities) sound.

I too have back up amps. I have the luxury of having several OddBlocks and Poddwatts around at any time. I also have several SS amps around gathering dust. IMHO real amps glow in the dark....if your SS amp glows in the dark... call the fire department. :lildevil:

Good listening
Bruce
