This was one of the best tube checkers Hickok made. Works good. The only thing that is no functioning is the role chart. BUT the maintenance manual has all the listings as shown in the picture. Also has the calibration procedure. The picture #4 shows it checking a 6U8. The cabinet is in \"OK\" shape, some pealing here and there . The handle and front latches have been replaced. Very nice gm Mutual Conductance checker reads directly in micro mho\'s and good bad scales. This unit is a little on the heavy side . I refund excess shipping cost back to your PayPal account. I charge only the shipping charges and will ship as cheaply as possible. Unused funds will be returned. No exports PayPal only (I need the room) :)
