Safety First
Be extremely cautious & careful with live Electricity, Charged Capacitors
and Exposed Connections, spacing-out is lethal
Always when working on energized equipment
Be slow, deliberate and methodical
When measuring live equipment, one hand in the pocket
the other hand holding the Voltage probe.
Even de-energized equipment can shock when Capacitors
Discharge and find a current path, right through your Heart.
Proper training is the responsibility of the Hobbyist
to learn from a proper safety curriculum
ShermanAudio is a Hobby, not a Business
If you need Safety Training visit the OSHA Website for lots of great resources
"Untrained people create problems, Clever people fix them, Wise people avoid them"
The message is not discouragement, but a realistic safety position on
working with exposed residential AC connections, PC Boards or wires
Safety example: Building external power supplies
If you want to create an external Power Supply solution great, but do it the proper way as shown in my illustration below
One never should create a Power Supply with exposed potentially live connections, the umbilical cord with the
exposed pins always is fastened to the Preamplifier while the receptacle that contains the dangerous
voltages is always installed on the Power Supply
Preamplifiers benefit from separate Power Supplies, but please do it right!
