Problem while designing LM386

[Bhargav_Katakam]

I am not getting correct when I created square wave oscillator using Lm386 .I have designed my own subcircuit for lm386 and later I tested it for square wave oscillator.
I am attaching the cir.out files of lm386 subcircuit and square wave oscillator.
Please somebody help me how to resolve it.

Please edit your post! If you want to show code (e.g. inputs and outputs from ngspice), put ~~~ (three times the tilde) at the beginning of a new line in front of and after the code. Otherwise it is relatively unreadable.

Example

r1 /3 gnd 1k
r3 /2 out 100k
r4 out gnd 8
v1 /6 gnd 6

of a code snippet.
