Here is a working tube tester by Heathkit - the IT-21.  Tests nearly all tubes - 4, 5, 6, 7 pin mini, octal, 9 pin mini, 9 pin Novar,... Yes, the roll chart turns easily and it's easy to understand the set-up.  Line voltage set works fine.  All toggle switches work smoothly as well as all rotating knobs. Shown testing a 12AU7 and a 6V6 I had lying around. Heard a loose screw or nut in the unit as I was turning it round and round while packing it. Shipping fee by distance from me here in 34207, FL.  Does it get any more fair? 
“Used working condition - tested.”
