"There were only a few types of tube socket, so it was easy to make a mistake." This sentence doesn't make sense. — Preceding unsigned comment added by 71.171.16.106 (talk • contribs) 20:08, 22 December 2015 (UTC)

"There were only a few types of tube socket; ... mistakenly exchange tubes with different functions, ..."

This is not correct, the function of a tube is to amplify(no matter the circuit), the problem is the spec's and wiring... for example the filament voltage, where a 6?? tube in a 12?? circuit with the same socket will burn out the tube.

An aside, as have been a repair tech, (not much with tubes) but from older tech I worked with, tube testers were a joke; that had the purpose to sell tubes. The good tubes would test as bad, and if you tested the new ones they would test bad. And full-fill pointless corporate diagnostic protocols (following steps even after its known to be bad).

I did work on CRT's and the use of a CRT tester was used for the rejuvenate feature and not testing the tube... as a bad tube was obvious. Ergergosdfghg (talk) 19:44, 1 November 2024 (UTC)

"only a few types of tube socket"

There were a few... if the picture of the RCA test was clearer you could see that. The problem was you had consumers that had no idea what they were doing; there was 6 and 12 volt filaments that used the same socket, as well as dual and single, and different grid config(as I vaguely remember), and numbers would get worn off. Manufactures selected tubes with the same sockets so they and technicians didn't have to sock so many different types.
