[Horace W. Hall]

Recently I bought some 6146 tubes and noticed that the reading stated out=

fine but then dropped after a few seconds or so of holding the test butto=
n
in.  It eventually dropped almost 40% after a minute or so.

I'm glad that you brought this up. I have had similar experiences with my=

Hickok 6000A & a few types of sweep tubes (6hf5, 6js6c, etc.) where, upon=

pressing the Test button, the meter swings to the Good side and then
plunges into the Bad side, sometimes quickly, sometimes more slowly. I ju=
st
had not gotten around to asking whether that was to be expected or
indicated trouble.
