Hi,
Thought I would share my experience building up a non-export version of the 251 with poctop's 251 boards.
I used a 5718, which sounds great and I highly recommend it. If anyone else wants to do the same, I ended up using a 2k74 cathode resistor, and that seems to do the trick. I also chose to under-heat the tube as in the original (~5.9V).
I'm still having some trouble fitting the body tube around the relays, so I think I'm going to have to file the corners down.
I also recorded a little test so you can all hear what it sounds like (we don't do that enough around here).
