[Test-Equipment] HP-606A Calibration question

[Carl]

Q Dope is still sold by General Electronics (GC)

As far as the 606A make sure that none of the plates have been bent. If so 
straighten them out. Ive yet to see the dial loosen up and use that as an 
absolute last resort. Ive overhauled many 606's over the decades and its 
rather easy to get the alignment within the dial line width by following the 
manual.
