Inside thee cabinet,,on the side wall,,(label), or give all these smart older / wiser - gentlemen -a tube line up,,,number on each tube in the set,,,just pull one tube out at a time and reinstall in same position,,watch -out for little key ways on some tubes on center post,,,some older tube have pins that are offset,(staggered),,soo,,look careful how you pull them,,,some take a little wiggle to get to move out of all thee pins-----but most of all----don"t, don't grab them by the glass and pull,,,sometimes you can read the numbers on thee glass without pulling,,,,this is just a start,,,,soo,,,cheers.
