281. [Amps] Shock hazard? (score: 1)
Author: Will Matney <craxd1@ezwv.com>

I know this don't necessarily have to do with amps, but I figured I'd show this as what not to do in building any tube application. Can anyone spot the shock hazard on the old CD capacitor checker? I

Hector, Making sure everything is RF tight and all grounds and shields are good is the most important thing. A dip meter could be used to find RF leaks run as an absorbative wavemeter. This is simila

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

Hal, I think that is the same as an electric cautery (to burn and seal off bleeding, cauterization or electrodiathermy). It's an old one by the looks of the insulation on the windings. I had some sur

Bill is correct on this. The reason I know a little about it is because my Grandpa and a friend had one. The thing is about Pacemakers, there's no way for them to be shielded by themselves (no path t

Neil, A few things could cause what your mentioning. A very rare problem with the coupling capacitor which is opening under load. 99.9% of the time, the failure is a short. A bad ground from either t

All the electric motors, less the DC motors, would have to be changed out to ones which would run at the higher frequency. That would be one way to lower the unemployment rates..hi hi....... One woul

Mike, The way it was explained to me, nerve transmissions run at a certain frequency and it was a low one. When I had the EMG a while back, they insert a needle deep into a muscle, close to the nerve
