oh ya, and @ ombuttsman: No reason to be shy man! Thats a fantastic build there, especially if its one of your first! Work quality looks stellar, and as was mentioned above, good job on fitting it all in there - I definitely had NO hopes of getting 9V#2 in there when I built my first cmoy (although god knows I tried in vain!)!
i appreciate your kind words!
but i hope someday i can build a hi-end amp, it's a shame here in brazil these high quality parts are REALLY expensive and hard to find. 99% of them have to be internationally bought via internet. even a simple TLE2426 is almost impossible to find here, that's why i used a simple resistor divider in this altoids amp.
but while i can't afford a hi-end amp, i'll keep appreciating yours here! keep up the good work!!!
My CMoy, which has kept me company for several years.
Nice work! I used a mint tin too, but am considering other options now. I need two batteries but like your design, mine has the audio jacks near the volume control which is a bit of a pain. The cables and jacks get in the way of my fingers...
I don't think it's possible to do any other way in an Altoids tin...

my first amp... I'm quite pleased how it turned out
edit:
So it's the M³ amp using 627s at the moment, the power is a s11 @ 36V, so I have some 637s on the way to try 637/627 on 36V, the main toroid is a Block 25VA 2x18V, I have a 25VA 2x12V on the way too so I can set the sigma11 @ 27V to try 8610/8610 and 637/8610...
The momentary to latch is an e24, powered by a mini 2x12V toroid... the M³ output goes via a simplified e12 muting circuit... as I have some polycarbonate caps on the input signal, I took out the DC offset protection part of the circuit and therefore the need to connect it to a +/- supply, so it's connected to the +/0 output of the s11 with a 7812 to provide 12V
The case is a Hifi2000 Galaxy Maggiorato GX283 with the optional 10mm thick panel, ordered from Italy, sent back to the continent to Schaeffer to get the front and rear panels milled as I didn't fancy even attempting to cut the rear panel with handheld powertools as it's anodised.
It strays a little from the M³ spec in that I have a more "commercial" bass shelf, using 0.047uF caps instead of 0.1uF so the difference is quite strong, and solves the anaemic upper bass of the K701 I tend to find for some music I listen to, the spec'd bass shelf is quite subtle and very low frequency
Building the M³ in such a small case was always going to be a bit of a challenge to fit it all in whilst keeping the power away from the input signal and the pots are off-board, so I kept all the audio cables ultra-low capacitance and silver-plated OFC / OFC mix to minimise the likelihood of signal loss or warping.
AMB/Ti, Ferrari/Duc, and Dougigs have all been very patient and helpful during my build
Very nice looking build hardnrg, but you might need to elaborate on a few things. I don't recognize the PSU, what is it? You also look like you're using a monetary switch, is that the e24 there?
