You should!

You've only got one life, so please don't risk throwing it away by saving a few $, and get some fully shrouded connectors if you build one.
Totally agree Simon - if I need them I'll get them from RS, Mouser or somewhere.

I suspect I'll end up building the first version, so may not need the banana plugs. I imagine I'll mostly want to test 6V6, 6L6, EL34, EL84, 12A*7. I'll keep thinking about it while I wait for things to arrive.

I'm contemplating non-battery power options for the meters, but I don't think it's something I'll be using very often so perhaps it isn't saving much waste to just go the battery route.

I also think he's a bit hopeful stating you can build it for under $100 - the 350V caps aren't super cheap, and enclosures, sockets, switches etc add up, especially if you need to add postage. I mean, it is still relatively cheap, but I don't think I'll get it done under $100.
