I just got and assembled valleman 118 rs radio I would like to add aux input to it. It uses lm386 so 2 and 3 are inputs. So I wonder if I cut line before + pod and add aux will cutting line and adding some wiress will accomplish what i want. ?

Tritron,

Welcome to the forum! In general it is polite to provide a schematic of a circuit in question when asking specific questions about modifying it. The assumption that there are people intimately familiar with any given schematic and can from memory give helpful suggestions is generally false, as is the supposition that someone will be eager to take the time to research a particular circuit to respond to an inquiry.

Now, onto your question. The LM386 used in this circuit is used as an output amplifier, and you might be able to modify the circuit to accept another signal; however, since PIN3 of the TBA120U is MARKED "AUX AF IN", why on earth wouldn't you just use that?
