[Amps] Shock hazard?

[Will Matney]

Arthur,

Your correct. I thought that was the anode cap on a rectifier tube. I 
couldn't figure why in the world they would have done that. Next time 
I'll look up the tube but figured it a diode. Still at that, it is poor 
engineering practice to do this. The eye tube, I can see as it has to be 
shown. I think if it were me designing that, I would have mounted the 
tube on it's side if it allowed it, or put the assembly in a larger 
case. Hal Mandel, W4HBM, brought up a good point about the line cord not 
being grounded. A lot of equipment back then was this way. The only way 
TV, and stereo sets get by with it today is using insulated cabinets 
being fiberboard or plastic.
