Vintage Hickok Dynamic Mutual Conductance Tube Tester Model 533 Audio Testing Equipment, Turns On! Comes just like you see in the pictures, so take a good look. The case is fairly worn but intact. Like I said in the title, it does turn on, but I did not have a way to test it beyond that. I did notice the power cable is stiff in parts and cracking a little, especially near the plug. This unit was an estate sale find. Sorry, no Buy It Now. Please bid! <...br>
