This particular amp just has a 2.5 inch 2watt, 8ohm mylar speaker and is for bedroom level jamming, or practice with guitar. I am sure it could play music as well, but I would imagine there is too much gain involved for such a use, and it would distort. Hope that answers your question.

Ah, that was a thought of mine. That the bottom panel included a speaker. And now that I think of it, the Ruby IS a guitar amp. That clarifies things perfectly, thanks. Wish there were such a thing possible for a bass as that's what I play.

funny you mention bass.. I have been working on a mod for a bass practice amp in this format. I will let you know if I am successful and will share the specs.. I am sure it won't be too bottom heavy but the goal will be to keep a clean signal and up the values on the caps to add more bass to the circuit. Speaker choice will be crucial as well..

Default Rough old box for LM3886 amp

Hi, been reading the forum får a while and this is my first post.
Thanks for all the inspiration and awesome stuff!

I Started my build around 8 years ago. But it didn't get finished. As it some times get.
The first one was hard wired. Thats the way to go back then with gainclones.
This time around i ordered X Y boards for LM3886.
I found a nice old electronics case. Its a old AC to DC converter. Like the rough style.
This is my so far markup.
What u think?

Not been hotter than 40 degrees celcius. But I'm still going to take some extra measures.

I think you are like myself in that you like to use old enclosures. A recycling type of a DIYer.
