The worst part was when the little stickers you put on the tubes to remember which went where fell off.
omg, usually you could just swap in a working one from another TV/radio. if it work you knew which one to buy. pins match, good
Just because the pins matched didn't mean the tubes were the same. Also, remember that the whole point was to take all the tubes out and take them to the store where this tester was to figure out which tube was bad. So if you didn't know where a tube went, swapping with another set (if you happened to have one) wasn't helpful because if was more likely to be a good tube.
was ten. m&d let me try anything. didn't work it didn't work
