NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
Because a hot chassis ground is present in the power supply
circuit, an isolation transformer must be used when repairing.
Also, in order to have the ability to increase the input slowly,
when troubleshooting this type of power supply circuit,
a variable isolation transformer is required.
