Where did you get that enclosure from? It looks like it could be pretty cool for a sub mini amp build
If at first you don't succeed... use bigger transistors!

Thanks John. You've got first prize on sturdy amp builds though. How heavy is your former staircase amp?

I was thinking that myself! The case is from my local electonic shop. Generic no name import. Hammond have similar ones.

The bathroom scale puts it at 11lb. It's not the heaviest amp in the world, but considering that it's 11"x11"x4.5", I should have said it is very dense.

What amazes me is how great the speaker sounds. It's an 8", 8Ω, 25W no name speaker that I bought from the local mom and pop guitar store for $10. The only thing I know about its history is it came from a small amp.

I'll bet that your opposing dual speakers give you room-filling sound (and they appear to be in phase, which is a good thing ;)).  I also notice that you can run it on battery or adapter, which is nice.

Nice one, Petter!  Good colors and the writing looks great on the black box. If I tried that it would look like a three year old wrote it!

thanks! yeah, when it comes to black plastic enclosures, i pretty much have to pull out the posca pens unless i want to repaint, and that's not something i'm too eager to do w/ plastic.

I finally boxed this up. Not much of a box but the circuit works nicely  :D . Its a Ruby amp but with two LM386 chips like the Little Gem MK2 so it gets pretty loud with a 10" guitar speaker, more than enough to annoy the neighbours.

^Well done!  I've done a couple of Noisy Crickets, but now I need to take a look at the Little Gem. ;)

This is my latest build. A JTM45 with some small modifications according to the clients' wishes.

This is my "bench" amp.

I had my good buddy help me with the birch box, as he is bad@ss with a saw. The speaker grills were from a small brass bird cage that i re-engineered. The oval w/numbers is from a medical thingy.
(I repair med gear for my steady job.) You may notice a wad o wire there. That is a wall wart I had to put in because  the 9v kept dying every other week!

The top is from a brass fireplace took stand. the handles I got from a flea market, The jewel lamp was from a mass order at Arizona antique radio supply.(i think.)
Those knobs w/the shell inlay were from a parts dealer on E-bay.
Here it is with a little lap guitar I built for my daughter.

Thanks, Mike. Your post reminds me of a Barbara Mandrell song. "I was steampunk when steampunk wasn't cool".  ;D

Here's my Firefly.   Testing stage, chassis not mounted. 


And finished.   You can just see the Boost Switch poking up in the back.  Controls face up at the back of the top panel.

Cheap guitars, homemade amps and garage rock technique.  But I have fun.

 AMPhetamine.



And with that, I'm think I've exhausted that concept. :)

EDIT: I forgot to mention, it's a smokey amp with volume control that i crammed in there.
