so it is a sheet of metal with those part on top?
or are those parts hanging down the bottom of the amp?
 
I hav read those pages and thought those are inside the amp, isn't it??

Yes.

They hang from the bottom of the metal plate that sits unattached (its weight keeps it in place) on top of the wood base.  So it's protected from the sides and top, but there's no bottom protection under the wood base.  So it could get damaged from below if you're not careful, plus have to make sure the metal plate doesn't fall off the wood base if it gets turned sideways or upside down, though some people screw the top down.
 
Really don't think I'd regularly travel with the Crack.

will making a protection under the bottome affect the performance?

It could if you block off the air circulation.  The amp might overheat.

I suppose you could make it removable so you only put it on when you travel.  But still, I don't think you want this jostled around much - definitely hand-carry not check-in!  Or buy a hard-case for it to protect the bottom - but still hand-carry though not sure what TSA will make of it.

I wonder if anyone has ever made a pcb version of the Crack?

 

[tdogzthmn]

Anyone here use an E80CC tube?  I have a Valvo branded one with the gold pins which sounds a bit brighter than the average 12au7 but I enjoy the clear sounding and detailed tubes.

Just ordered a Crack kit the other day...and finally finished reading the 59 pages of this thread.  Thanks everyone.  Great info.  
 
I haven't soldered in about 30 years, so this should be fun!

 

[Hughkk]

thanks everyone.
i think i might put my crack in home and get a solid amp like m-stage matrix or asgard to travel.
 
Well that's expensive

 

[skeptic]

Sounds like a good plan hughkk.  For travel - you might also consider an O2.  It is transportable by design, and I suspect it measures quite a bit better than the asgard and m-stage - for about half the cash.
 
As far as putting some protection under the bottom of the crack - a screen of some sort would probably do the trick without creating heat issues.
