I don't understand why that trim cap gets so much attention.
The first and the easiest to check is the detector diode considering it to be an AM radio.

Next check all the 3 transistors in the converter and IF stages.

Thanks for the information! I'm still kind of new to this so you'll have to explain the detector diode to me.

I'm learning, I'm learning......

Thanks again!

The block diagram of a radio receiver will consist of an antenna, a converter, IF stages, a detector and an audio amp.

If u trace the hot wire of the volume control, u will most probably reach the detector diode. It will be two leaded glass(maybe) encapsulated component. just unsolder it watching its which-lead-goes-where and cold check using a DMM. It should show low resistance in one direction and high the other way.
