You could increase the distance between the power and input a little more. You could also add another cap.

Default latest pcb for ksa992 and mpsa92

Hi Harrison,

Previous layout of ksa 992 pin configuration is wrong it should be ecb however mpsa92 can be used.I also forgot to include c4 and the 2 protection diode.In this latest layout I have produced two boards for ksa992 and mpsa92 and also included your suggestion.I have included also my schematic as reference.

regards,
joel

p.s.

pls. check my work.
