Hello Everyone !
I got this transformer in picture from my pal . . . It was installed in an old model cassette playing music system with a cassette loader carrying a stereo head , a 12v old motor , couple of leaf switches and an audio amplifier board with IC 4440 . . . Now Transformer inside has no label as you are able to see in figure below, but here with 250v AC input the unit is showing AC output of about 14v and the primary coil resistance value showing 85 Ohms & Secondary Coil approximately shows 20 Ohms, all on a digital scale . . . . . . . .
Issue here is the unknown power rating of the unit . . . . I mean to say that when I usually go for a purchase, I use to ask like => Sir, Please get me a 12 volt 1.5 Amp transformer or get me a 9v 250 Amp transformer and so on like that . . . . . . So now how to determine the actual rating of this local made device ????
Please help me finding it out for power rating !!
Thanks !
