Mine only took a few weeks to come from Edcor.
You can spend your time getting all the other items together and take your time building it. Good luck and post some pics

Core32,
  I just checked my notes and it took 4 weeks for the transformers to arrive. I spent most of that time thinking thru how to build the amp. Not all the part from Mouser shipped at the same time also.
While you are waiting you can layout and make the case. Think of any other options you want to include. I added a stand by switch to my amp. I can keep power to the tube heaters while not having the whole amp on.
 See my post "First time build" to see what I did. This was the first thing I ever built. Also there are parts needed that are not listed to complete the amp.

Edcor output transformers ordered.
I'm going to use a Hammond power transformer to get a head start on the build while I wait on the Edcors.
Mouser keeps several mA level selections in stock to choose from even in the 2 secondary model.

WOW! 19 days is fantastic, Take your time bulding this. It is fustrating making a mistake and having to correct it. I made a few while building mine. Post some pics while you go along we love to see pics.
Good luck

So I just completed a p-to-p prototype build on a piece of composite board for a test run and beauty fit check.
Testing voltages and such to see if my 5U4G-B rectifier circuit was designed properly.
Voltages are a bit high, I believe, due to the loads being less than what I planned for.
Anyone have a method for estimating (or actual measurement of) the current requirements for the ZKIT design?
I decided to load up all the tubes for a test run and...............Holy Cow!
What an unbelievable sound from 2W or less!
Zero burn in time so I expect it to only get better  :)
My grounding scheme just to get this running quickly is, at best, very weak, but I have to say I hear zero hum until I turn the volume up to near 95% with no input.
I have a question. My DAC can be configured as Fixed output or variable.
What is the best method for controlling volume with the Zen? Turn it up high and use the DAC variable out? Or fix the DAC output and use the Zen volume control?
Holly Cole is singing in my room right now but it sounds like she is up on stage and further back than my walls would allow  ;)

Thanks Lon.
It's going to take some will power to tear this apart now and get it into the real chassis...  
Just enjoying the image I get and it's only 5 hours old
With this crappy grounding I will likely go with keeping the Zen at a constant no-hum volume and adjust the input from the DAC.
You are correct of course that once I have the build solidified, whatever sounds best is the way to go.
I am using SV83s so I will be experimenting with the Hazen grid mod tomorrow.
I'll have to read some more to get the opinions on that as far as effect.

Well the Edcor power transformers finally shipped so I can now finish both builds and replace the weaker Hammond power transformer.
I decided to build two identical amps so that I can build the first one while continuing to enjoy the prototype.
The majority of the parts for the second amp will come from the prototype.

And a different angle.

And the last pic for this project.
Very happy with the sound from these now, including the updated components used over the kit level.

BRN,

Edcor, XPWR178 in case the link doesn't work.

Nice build!

Core32, what meter did you install on your amp? Catalog number?

Thanks Core32, sort of a toss up between round/square. If I add one I might just have to flip a coin

Hey Core32,

What size case did you use for the amp? Would you make it larger if you did it over?

Thanks Core32
