Hello-
I have noticed over the years that the 6BE6's I test when pulling tubes
out during restorations do seem to be reading lower on TV-7 tester.I prefer
to use the JAN 5750, and have some 5915's, but as I recall the 5915 is in a
taller envelope. I need to double check on the 5915's, have not tried any
yet. Thanks, Byron WA5THJ
