B&K 470 loose socket?

[Dreamsbeard]

Hi all,

I just bought a B&K 470 crt tester of ebay, and tested a few tube with it (with the #23 adaptor) and then I tried to test a crappy 1995 zenith , still with the #23 adapter, then nothing... I was able to set heater voltage and G1 voltage , but not the G2, and of course I could not test the guns... One thing I noticed is the #23 adapter that I placed on the neck of the tube was very loose , as in "if you touch it it will fall" loose. Could that be the problem? Is it common to find a tube where the adaptor for it is so loose that you can never test it right?

Thanks!

Carl
