How to update Johnson Viking II Ham Transmitter AC power Safety
Many older electronic devices came with unpolarized AC power cords. Back in the day that was OK as the manuals came with specific proper grounding instructions. This however, does not eliminated the possibility of being shocked. The same issue is famous among-st tube guitar amplifiers. Many reports of players being shocked from a HOT chassis. A very dangerous situation which can easily be remedied with a modern 3 prong grounded AC cord. The procedure takes approx 1 hour. The result will be a layer of protection to eliminate you from being poked. As you can see in this video the hazard is present even if the device is NOT powered. Also a good practice when servicing these devices, ground them to protect you and your test equipment. Hope this video is of value to you. Remember, this is presented as an option. Some consider this a modification, I view it as an upgrade.
