trying to figure out what the output of this part will be

[beanboi]

So i happened to get ahold of a gbu605 and a few diodes, a transformer, and some capacitors,
i dont have a voltmeter or anything and i wanna make a phone charger just because. my idea is that supposedly the gbu is a 600v 6a bridge rectifier. its a stupid idea but if i hooked 120v 60hz ac into the ac part what would be my output in dc?
how could i build a circuit for this

"Rough" DC, peaking at around 1.4 x the nominal AC voltage.
(The AC is given as RMS, not peak).

You need a transformer from 120V down to around 8 - 9V, then rectify and regulate that.

i found this mystery transformer with digits on it but i cant identify this specific one. it appears to have a us mains cable on one end and two smaller wires from the secondary each have 300v capacity idk what is comes to tho
the digits are DB-EI28-6836A

i could try to find an lm7805 bc im familiar with it
but otherwise idk about the transformer

It sounds like you're about to blow something up. I'd stop now if I was you.

wouldn't be the first time

That sounds lethal. Don't use it if you have no meter for checking its parameters.

Unusual method of design. Please tell the outcome, if you are still there.

and two smaller wires from the secondary each have 300v capacity

how did you determine this?

 

[rjenkinsgb]

I'm guessing that's just the ratings markings on the cable insulation?
