Here have one psu for monitor with model 7575+TL494

ERP:6003070043

I know that`s not exactly the model but only that see on the board.

Where to put the Light bulb instead - f901 or NR901? I am almost sure it`s F901 but let me ask

 

What??

 

Put the light bulb in series with the live mains wire going into the item tested.
