1. For optimal audio performance, C11 (0.33 uF & V>=10) should be an aluminum electrolytic capacitor with the positive
2. If the loop current is never more than 60 mA, Q4 and R7 may be omitted, and R5 and R6 may be 2.2 .
3. Do not replace Q2, Q3, Q4, R5, R6, and R7 with a single transistor of PZTA42 type. Power transistors with a higher
4. C10 and C14 need to be NPO if V.90 modem performance is required. Otherwise, it is more cost-effective to use X7R

the PCB is less than the typical 0.062” thickness and there are vibration sources in the application.
EKMG500ELLR33ME11D is an appropriate alternative in this case.
