ilikepie116 that's pretty creative.  How does that effect the sound? Are the "sound tight"?

wdahm519 - Nice looking build. And yes the EHHA is something special.
I don't see it mentioned but did you incorp muting delay/offset protection? Unless you never forget to unplug cans @ power on/off think the design really needs it.
BTW guess you did individual transformers for each channel, because I was able to get by w/5-wire umbilical (+/G/- DC amp, +/- DC heater).

No I didn't incorporate and kind of muting delay, I'm pretty religious about letting my amp warm up for the proper amount of time before plugging cans in, and I always unplug them with the music off and volume turned all the way down every time.  It's just habit now.  
 
I measured the DC offset at the output and it took a short amount of time to reach safe levels and about 2:30 min:sec to fall to very safe levels where it would be come absolutely stable, however I wait 4 minutes before plugging in headphones.  Its better than my Bijou.  That amp makes me wait a full 12 minutes!
 
I have the same set up of transformers you do (30-0-30 AC, 9-9 AC) but I ran other wires from the transformer through the umbilical in case I want to add something later to give it power in different configs.

KGSSHV coming along nicely... just need a functioning PSU
 

 

[ujamerstand]

Looking good!

 

[jdkJake]

Indeed!

Are those heat sinks fully enclosed in the chassis or are the sides open as well?

Is that a Khozmo or an RK50?

 

[El_Doug]

It's an RK50, and the heatsinks are fully enclosed - will be a fun time with the CNC machine venting the top and bottom  

 

[jdkJake]

I look forward to seeing the end result. That should be one sweet build once it is up and running!

I am particularly interested in how the internal syncs work out. It appears to make a nice clean package vice external syncs.

Woah El Doug! That is nice!

Nice Doug!
 
Looking forward to hearing it at the NYC meeting in June

3rd gen ICE 125ASX2 monoblocks (250W@8Ohms, 450W@4Ohms), with AMB A20s as input buffers and Cinemag transformers for SE-BAL conversion. All cables are shielded.

...and my M2Tech Evo Salas Supply (aka MESS).

cute!
 
I need to build a supply for an EVO myself...
good that I have some of the Salas boards around, too.

 

[tranhieu]

nice! how different does your evo sound after having the new friend?

 

[TheShaman]

Thanks guys!

It's worth it. The power supply is almost three times the size and weight of the EVO itself but who cares...
Was actually tempted to go with batteries but charging management issues made me go for a mains-powered unit.

Well, the distributor here only ships a switching wall-wart along with the EVO. Compared to that the difference is significant (granted we're talking about a device that has a very specific/limited task in the sound chain).
Less "edgy" highs, a recording's ambience is more evident and there is also a difference in soundstage (which is also surprisingly evident with headphones).
