Can anyone take a photo of the demodulator board (bottom of the reciever - middle towards the front)? I am trying to repair mine, but it's got some added components on the board that faces that bottom and I'm not sure if they should be there or someone tried to "improve" it. It's never worked and I can't imagine the factory doing a sloppy job like what I am seeing...

Here's a photo of what mine looks like. https://image.ibb.co/jwPN0a/20170323_220212584_i_OS.jpg

I don't have one, but wow! The transistor looks like it is not soldered well and maybe a lead is shorting to the adjacent one. It is a transistor of the right era though. The cap looks newer. The spaghetti looks original but not often covering the whole body of a resistor.
