DIY is indeed the issue but this one was designed so that pretty much anybody can build it. You can get away with little to no matching and all of the parts are relatively easy to source with a large majority in stock at Mouser. There are some teething problems with the first boards but they will be worked out as soon as the crop up.
Now a KGSSHV in a BHSE type of box will cost pretty much the same as the BHSE. A chassis of that quality costs a lot to make so any savings would just be down to the tubes and sockets. The onboard version (where the heatsinks are located on the PCB) can be fitted in a 2U chassis/400mm chassis from Modushop and it looks quite nice for 50€.
Hum, you are tempting me... but the closest I got to make something like that was when I was still playing with legos! Well, perhaps I should at least take a look at the blueprint (which I think I saw on this website somewhere, is it possible?).
Besides, I assume that if you were to pay 5000K on an amp you would go for the BHSE rather than for the KGSSHV in a BHSE chassis (to drive the MK2 in my case), right?
At any rate, thank you very much for your answer Spritzer, it is much appreciated.
