CAUTION ! :
For continued protection against risk of fire,
replace only with same type 4 A, 125V fuse.
4A/125V
ATTENTION : Utiliser un fusible de rechange de même type de 4A, 125V.
NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
8-8
Because a hot chassis ground is present in the power
supply circuit, an isolation transformer must be used.
Also, in order to have the ability to increase the input
slowly,when troubleshooting this type power supply
circuit, a variable isolation transformer is required.
