Behold, Phil Nelson scribed on tube chassis:

I'll be a contrarian and ask, Do you really need a tester?

Hi Phil,

I do no repairs, but design from scratch, so yeah, it'd be handy ;-)

I have over 1,000 tubes with many onesies, so I can't really sub too
easily. Example, a tube regulator drove me nutz. It was a bad 6AU6,
'cause when I rewired for a 6CB6, it worked :-)

Cheers!
