Ian,
I'm in the process of building up a set of tetrode boards. You can
view my live stream page for videos during assembly:

I can say I didn't have that much difficulty finding parts across the
pond. Mostly ordered from Digikey and Jameco. My challenge though was
with the PCBs - some newer components have smaller footprints than
when the boards were originally layed out. That hasn't been a show
stopper for me.
73! Mark KA6WKE
