Default Re: Ampro Stylist projector

It is indeed with a live chassis.
I have the isolation transformer ready. So that is taken care of.

My problem is the "power supply".
It's a pretty weird way of doing it to my eyes.

There is no step down transformer.

Granted, I am a beginner. But I've done another projector and a couple of radios already. But this construction is weird for me, so I am asking.

I've attached two pictures of the bit I'm having a problem with.

There's a 2in1 resistor in the voltage in circuit... I don't know the proper name of this.

The purple wire is the 245v input and goes through all of the 72ohm resistance.
The white is 225v goes through 34ohm
And finally the bypass is wanting just 205v in.

There is also a 500 and a 600 ohm resistor in the chassis.

The 2nd picture is the 4 pin input.
I'm unsure which is phase, neutral and ground...
I'm going to scrap this part since I'll be installing the isolation transformer. But I'd like to know which is which so I can wire that correctly.

I'm asking as to not die. So pardon me for not wanting to die and asking because I am uncertain. I am trying to get the consultation that I need
