-1Meg ohm resistor +  * 1Meg ohm resistor

 I have mounted the components on the circuit board with hot glue and connected them "​ugly"​ style. I found with a correct narrow deviation adjustment adding a 38k resistor gave me a wide band setting. you can replace this with a 50k pot if you require. I have mounted the components on the circuit board with hot glue and connected them "​ugly"​ style.
