My reverb unit was not sounding as good as I would like so I thought I would give it a look.  Turns out all it needed was a couple of new preamp tubes.  I have the thing on so much every day that I guess they got weak.  The new tubes brought it back to life although you probably can't hear the difference on this video.  I show how I use my Hickok 752 tube tester.  I could not survive without that unit.  I have never had it calibrated so I am not positive it measures the tubes perfectly but it does what I need it to do.  It allows me to cull through my box of tubes until I find the best ones.  Hickok made some of the best testers.  I think this unit was made for the FAA back in the early '60's.  It is a high quality, well made tester.
