oh wouldnt it be amazing if it had the thermal conductivity that you could use the copper tube as a heatsink that was good enough for a dynahi. coz thats the perfect sort of enclosure for such an amp!

The Gainclone power amp i'm planning has just that funtionality, although the copper bars are central and the enclosures are mounted outboard with the chips mounted in such a way that the copper tubes cunduct heat away from them. I've not looked at the dynahi but i'm sure it's do able
the design is basically a Pimeta clone, a pimeta in a MINT!
it is not fully completed yet since the volume control pot is by-passed, the CRD for biasing op-amp into class-A is not installed, and most importently the thing is not put in a mint casing yet.
the surprising thing is that it runs on the first try! (although I have tested and corrected multiple error b4 acutally running it, including a spoiled OS-con).
This amp is actually my warm up for the coming PPA clone.
I was thinking of trying something easier first b4 actually solder the PPA, my PPA layout is already standing by...
As I progress I believe this amp can actually be more difficult to solder due to the density and the number of cross junctions.
Just thought I'd show my Zippo lighter tin cmoy amp, wanted to use something different to a mint tin.
Fits well into the Zippo, the PCB design was originally by Guzzler, built using a home etched PCB, with rail-splitter and opa2132pa op-amp.
I am in the proccessing of making a cmoy amp in a zippo tin, as well. I unfortunately have terrible soldering skill when it comes to close quarters like that, so i decided to go sans-volume control and use an input pigtail to make it easier, but then i've come down with mono and can't really work on it anymore i could always put my all-radioshack amp in there, but it picks up the local AM radio station

Here's my brand new pimeta. I used the 8610/8620 OpAmp and the 634 buffer. Also, I used the Serpac case with the belt clip. I got the PCB from Tangent's site, and the build was very easy. As long as you have soldering down, building a pimeta on the PCB is almost easier than building the Cmoy on a generic board.

whoa, for your first amp that's done really well.. it's so small! i tried really hard to make a small cmoy.. must've worked 5 hours on it.. kept soldering things in the wrong place.. finally finished it and it was horribly out of balance..
anyhoo, good work! i love small amps like that.. just need an inline volume pot now
Linear Mode
