I think that it is probably much better than though. It is about from the back of case to front middle knob. The knobs on left and in turn easily but knob right is a little harder.
The case measures x oz. I was able to hear a signal through the oscillator using headphones, but since don't have experience properly test it and can't guarantee how well functions, am listing as parts repair with no return. This Hewlett Packard hp 200C vacuum tube audio oscillator is in very good vintage condition. You can my photos to see the very good condition that it is in.
It is quite heavy for its size weighing about 23 lbs. It powers up as can be seen in my first photo.
