Zzzzap! Ow!
#1

Well, this just goes to show us all that even a restored radio can still have its dangers in the oddest of spots. Basically, I have decided to get all my US Apex radios going and first off was my buddy reviving my Mantola 27 that croaked on me a few months back. Turned out the original resistor in there had somehow shorted against the chassis and blew the new electrolytic that had been put in. After some work, it performs even better than before and is once again here in my bedroom. Anyways, I was tuning the radio earlier today before work and hand my left hand resting on the opposite side. Now mind you, these use a metal thumb wheel for tuning, so there is no insulation between you and the tuning capacitor! There are three decorative, metal rosettes around the speaker that are also the heads of the speaker mounting studs. I let my left thumb go against one of those while tuning and.. YIKES! I pulled both hands away immediately! Took me a moment to realize what I had done, basically created a circuit between the tuner and speaker! Also reminded me to always be careful with these earlier sets as there is not as much isolation in them as later, transformered sets. There is reason why materials such as wood, bakelite, and plastic were popular for knobs and it wasn't just for looks!

No matter where you go, there you are.
