I love the case.  The contrast is great, with the maple and walnut.  I love that you went with curly maple instead of birdseye. :)  I love figured curly maple.  It's going to be really pretty with the polished top.  Don't scratch it assembling!

scratches... so far the wood isn't scratched. Small but visible. The bronze is delicate.  I know not to attempt to polish because it's sealed. 
It's just going to happen..
 
 
The assembly is progressing nicely.

Congrats, buddy! Can't wait to see it.
 
While you are busy with assembly, you should be thinking about the very first song you will play thru that fully assembled, magnificent amp.
 
It's a virgin amp and it needs a special song.

Lights are on but no one is home...
I suspect the input wiring got switched.
 
I am toast.... It's going to have to wait for tomorrow.

Don't forget to ground all metal pieces (safety ground).

Thanks.
Yes the top plate ties to all the transformers the backplate is ground to the power entry module both are terminated to the PSU ground lead.
 
I'm pretty certain I mixed up the RCA input terminations on the Driver Board.
I threw cation to the wind and sealed up the bottom prior to testing....
I think that rule number one..

Notice I scraped the raised domes and went with just the bronze screen

I like the screens. What's the red stuff under the transformers?
 
Yeah... Rule #1: Don't close up the amp until you've verified that it works.

Wow, that is nice!  Your craftsmanship is second to none.  Like every one else, I look forward to your posts! 
Can't wait to get a good push on mine.  Have the 300B power supply done and the  21st Century Maida regulator 90% finished.
I plan on using mine to drive some speakers in a small room.
