Our son brought his amp back to Santa's work shop for an early Christmas upgrade 30+watts/channel triode connected. (It was his stocking stuffer last yr). Cost to build: output transformers $130; 10lb power transformer $30; 6JN6 tubes $28; 6AC10 tubes $10; 12 pin sockets $15; choke $15; PCB $6(transfer toner etch method); wood frame $12; Alum top and bottom $15; front switches, knobs, meter, nixie $45; internal PCB components ~$100; Back side terminal posts power socket etc $25
I would guess in the $450 ball park... and then there was the beer for the elves....

George (tubelab) is a member here, just shoot him a PM to find out what the availability is like if you can't find it on his site.
He's quite busy these days, but is generally quite prompt if he is around.

Check the tubelab forum to see what's up over there.

The design is excellent by the way, and will get you to a very nice amplifier with a minimum of complications. (True of any of his amps actually)
