Question on a Hickok 505A oscilloscope

[Username1]

I agree old medical equipment is very creepy. Old electronics however has that Sci-Fi mystery look to it. I for example love my old Hickock Oscilloscope, I think its got somewhere between 20 and 500 tubes tons of knobs, a sweep delay that is very much looking like a combination lock dial, a big RED pilot light, metal toggle power switch next to the pilot light, and a 8" fan and air filter in the back. And oh-yah 2 handles on top and weighs about 100 lbs. And has a IIHS 5 star crash test rating from the institute of electron tube safety for all the tubes inside.
