Besides the obligatory Jacob's Ladder shot, this picture shows my home
made, 0-140 volt, 15 amp power supply. The parts all came from Newark
Electronics and include a variable auto transformer (variac) 0-15 amp
and 0-150 volt panel gauges, a 15 amp magnetic circuit breaker and a 20
amp RFI filter all stuffed into a ventilated case.
Warning: auto transformers are NOT isolation transformers, the output
is hot with respect to ground.
