It's coming along nicely.  Just about ready for my resistance tests.

If you left off the 8.2K resistors (it sorta looks like they aren't in there), then the amp will work but may be a little buzzy.  This may go away with installation of the C4S upgrade that I see in the background.

Hi Paul,

I was originally trying to save room on the top lugs for film bypasses on the 22uF caps, so I mounted the 8K2 resistors in-line at the bottom:

Later I concluded that the C4S's would make bypass caps unnecessary so I left them out.

I put the CS resistors on the ends of the flying leads for the C4S boards for now, as my case design will make it difficult to get to them after-the-fact.  (I now fully understand the appeal of everything-on-the-top-plate design. ;))

Cheers,
Jeff.

Ah, nice, you tucked those away nicely. 

The top plate design sure does make things easier to build. 

A 22uF/450V axial cap will also fit nicely and sit between the two T-strips if you want to complete the look a little more ;)

Finished base kit (haven't installed C4S yet):

That looks classy! Love it.

If I may suggest something, I feel the knobs are an eye sore. Metal knobs would add to the class factor and fit in with the overall design. Just my opinion. Still looks very nice.

I think the Dakaware knobs are cool.
