transformer ratings ??

["nitro2"]

Hello group,

I have got an transformer which is "gone" but without a output rating 
printed on.

It is ;

BILLION

94TS-117A



It is a shielded taiwan or korean transformer in the typical yellow-ish 
color with a glued-on mu-shield input is 230V ac , but output ?????????



Can anyone tell me what it should do ( v and amp )


thanks
