Can the MINT fit in that Hammond (I presume the smallest version?) without cutting?
Yes, but you will have to use smaller caps. I used 470uF Panasonic FC's, and they are too tall to fit. 220uF will definitely fit, but not sure about 320's.
Also, wiring will be more of a challenge as there will be less room.
My new mint, I put together in 1 evening, case work and all:
It has the 8620 with the 634s and has been biased into class A using the CRD. I also used a 220Ohm resistor for R11
The PPA took a lot longer:
I added the Bass Boost, and the crossfeed. I'm probably going to get a new volume knob, and another switch to make all three switches identical, but it's working great.
I used 6 of the 5002 buffers and the 8610s
The most difficult part was the crossfeed. It had 16 wires and it was large enough to make mounting difficult as well.
Here's my pc switch box. I know, this is my first soldering project and the pictures suck. I made them with a friends crap digital camera and yes, I know I need to buy one myself these days
Anyway, it just a simple box and it switches between a cdp or pc as source and my headamp or speakers as output. I might add the buttons to mute my mic later but that means I need to go to the shop... man, vacation makes you lazy
Btw those wires are solid and I believe I won't be using them in the future anymore. They leave to much stress on the soldering and they are just too difficult to work with.
On the Couch: Teac PD-H300 -> NONOZ III DAC -> PPA/Millet Hybrid -> K501/SR325
On the Desk: iBook G4 12" -> META42 w/ AD8620 -> HD330/B&O Form2
On the Move: iPod Nano 8GB -> EX70/ER-6
In progress: M3, Zen, JLH and a new DAC (and more...)
I built my first DIY project today, a CMOY headphone amplifier. It proved a little more difficult than using tangent's guide, as I had to use regular strip board, not the fancy stuff that you guys in the US have access to . Also, I had problems soldering, as my iron is a cheap one from Maplin, and it probably needs either a new tip or thowing in the bin . Also, I don't have anything to hold things whilst soldering, so that was fun .
Anyway, here's a pic:
Tomorrow's project - see if it will fit in the case I have put aside for it...
the K-12M from S5 electronics in a custom aluminum enclosure painted... an odd color and then clearcoated. even though the electronics part took me just one day to complete, the case and some tweaks/improvements took the whole holiday break!!!
the amp drives my akg's like a dream. it put enough bass in those things to make me completely satisfied with both the quality and the volume of bass! unbelievable, no?
the power recepticle is a 5 amp EMI filter i picked up at hsc, which goes to shielded (thanks aerius) transformers to a cheaply tweaked out board in triode mode, then out again on the cheapest rat shack jack i can find (yeah... i'm cheap) with a pair of 5 ohm wirewound resistors to sort of match the impedence. all of this is switched on and off by a heavy duty 15 amp switch (just so it can make a loud clicky sound)
I'm kind of impressed ( I like it , it's very beautiful to me )
I really wonder how it sounds on akg k501..
It could need some covering lid though on the front to prevent damages..didn't you think about building one for it?

i'd build a lid cover thing for it but A: i'm too lazy, and B: much of it will be exposed anyway due to ventilation. in retrospect, that case i chose wasn't the best choice, considering i spent a grand total of 5 seconds thinking about it. anyhow, i figure that as long as i'm careful and i put a warning sign up, everything will be hunky dory.
as for the sound, it's hard to compare since the best headphone amp i've ever used is a go-vibe. but first impressions on it is pretty much really really good. the detail is immense, and i wish i had a better source to compare it to (emu0404 is the best i have). the headphones also sound very dynamic, adding a bit of extra depth to a not-so-deep soundstage. but the thing that hit me the most is the bass. it's there, rearing its head very prominently. it's tight and it's detailed. i am very impressed and quite happy with it overall.
as for the highs, it did something to it that's hard to describe in words. for some reason, listening to the headphones with the govibe made the highs fatiguing to me; it made me want to stop listening to it after an hour. with these headphones, the highs are... just right. no fatigue. it's detailed and crisp as it should be.
to the mids, vienna teng never sounded so good. but uh... that's all i can say about it for now.
i'm not sure, but the overall sound may have ended up faster, ie, the thumps of a drum or the strumming of the guitar begin and finish without me thinking it's sluggish.
i personally think the k-12m is well worth the investment if you are willing to tweak the electronics a bit.
