Thanks guys, I knew it was gonna be good, had no idea though.. it's *really* good

Pics would show nothing special, just a few boards and some messy insides until I get it cleaned up and re-cased.

This thing is like a bottomless pit of awesome. Such power and presence, warm and fast and no top end nastiness at all. As you might guess, this is my first ever hi-end phone amp and I like it a lot.

It is my understanding that 2 x 115V primaries designed to run at 50Hz is the best semi-universal solution, without the transformer getting really huge and having a stupid number of taps on the primary. But for an investment like this, I want to get it right!
Well, most of stuff I build are dual voltage(hope one day to go back to Europe).
Dimensions: 110mmX93xx51mm
Paper that came with them does not mention frequency anywhere. Might be worth asking to be sure. I know Plitron specs says 50-60Hz.

That is brilliant. Thanks again zare!

Seems I could fit a pair in my Buffalo when it finally makes it into its new home, but shoe-horning one into my MMM is a no-go......

Thank you all.

Thank you all.

Really, I had no idea how much better a top tier amp amp was compared to what I thought sounded good. I don't know if it's a particularly good synergy with my orthos but the sheer clarity and ball-grabbing bass is quite phenomenal. Hooked to the Pico DAC it provides a level of performance I hadn't heard before.

Meet conditions are far from ideal so even great amps I'd heard there sounded no better than my old NAD/Hafler combo. In the quiet of my own space and time to suck it in is an eye opener. I know to a lot of you this is old hat and many of you have had amps in this league for a long time, me? Total awe!

Darn, I somehow forgot 100uF caps for C9-12... It'll be another $10 or so from Mouser, but then again I also messed up with C2-C5 for different gains. I got lucky with 8x and 2x. I'll probably go to Radioshack and see if they have any 100uF caps. Later on I'll probably replace those. Hope it won't affect the performance too much.

Edit: Hm probably won't work eh? They're low impedance caps.

Yep, it scares me when I notice I'm short on something, and then realize that it's for another board... (the 3.3V and 5V regulators, same family) I even ordered 5 too many SMD caps!

Great job on your β22 smeggy, it makes me even more excited!

Speaking of disasters.. I'm about to order another S22 kit for another amp, anything I need to be aware of before I start on it? I don't want to go through this hell again.

I'm not good at giving other people advice, so can I just say what I do?

A. I don't work at the bench if I don't feel some good chi happ'nin'(tired, hungry, mad, etc.)

2. I don't even think about starting until I got everything I need to complete the whole board. Everything. If possible, I do sometimes have extra parts on hand just incase.

III. I study the instructions(I've got some parts of Ti's website almost memorized), which will include proper orientation of components, including DIODES (lOl, I'm messin' witchya). More often than not, I'll print the instructions out and put in lots of pictures and diagrams, and have the computer tuned into the website or thread giving more info.

Last: If I have a question, I ask someone for help or look online until I'm sure I got it. If I don't understand and the chi is running low, I stop 'till I got it down. If I had to guess, I would say sometimes, not always but sometimes, that for every minute at the bench I've probably got an hour doing research.

heh, yep

Digger, thanks for the advice. At least I have a working one here to copy so should be easier than guessing
