Heathkit TT-1 Mutual Conductance Tube Tester w/Upgrade TTA-1-1:
$400.00
Beautiful fully functional High End tube tester. Takes 117vac. Comes with all manuals plus restoration & Calibration instructions.Top has minor scrapes from storage. Sockets and switches all working properly.
These were eventually bought by WESTON and is part of their top 3 units if I read correctly. VERY GOOD TESTER and my favorite but I need the space.
