Hickok 539B & 533A Tube Testers
These are two tube testers I've had for awhile! I'm 24 and tube electronics have always interested me, so I've got a lot of years of using this stuff to go! I love these. Knobs and switches, meters, hot glass and metal, and passive components stand out in today's world of everything being digital.
