Has anyone had to pay any duty on them at all? A froend and I ordered a half dozen boards totaling about 140.00 including the shipping.... I'm building both the balanced line stage and the Marantz line stage. The balanced ls will get the all tube regulated supply. My friend also ordered the MC/MM phono stage which it turns out is a grounded grid type preamp.
The only real differences I've noticed is that the tone control stages are deleted from those designs that had them. Also, Its not very difficult to assemble a pcb from a provided schematic unless you're not used to reading schematics.... These are not kits with step by step instructions...
Odd tubes? I don't think so... they are all readily available from a large number of U.S. distributers. 12B4 is about the oddest(if you want to classify it as that)tube I see in their stuff... otherwise its all pretty run of the mill.
There is another guy at
www.kitsparts.com that has all the schematics and parts lists on his site that you can download. In addition there is
www.liteaudio.com and
www.diyclub.com that all seem to be in kahootz with each other. Most of these boards are also sold assembled. It would be a fun trip to that store thats shown on the web sites..... They have lots of high end parts displayed like meat in a supermarket is displayed over here.....
