Strange portable, strange problem...

[darklife]

Got this radio from my grandmas house. It's a cute little radio and it is unique.
What you can't see in the picture is on the side of the radio it has two separate volume controls, one for each speaker, and one that has the on/off click built in. So in a way they are volume controls and also a balance control.

Problem is the thing doesn't go into stereo. The stereo light will not light up no matter how close and powerful the station and their pilot signal.
I opened it and checked for a faulty mono/stereo switch. It's fine.
Tried using the headphone jack to see if it was stereo only through cans, doesn't matter.
Checked for old dried out capacitors and any bad soldering joints and they all seem fine.

So what gives?

I have never seen another radio like this and would like to get it working. After googling for some time I can say that there is NO information, pictures or jack about this radio out there.

Brand: Tozaj
Model: TP 100, made in Hong Kong
AM: 530-1650Kc
FM: 88-108Mc
Dim: 6.5" by 3.5", 1.5" depth (it's little)
Built around the AN7420 chip.

AM reception on this little bugger is pretty darn good so I'd like to fix this.
