Re: Q1 Motor Diode Chips

I have found a replacement MOSFET transistor pair chip (8 lead device) for the one in the motor driver H-Bridge on QSI Revolution board used in the Walthers N scale Mallet loco.  I replaced the blown chip, and that fixed the decoder.  But the transistor pair chip on that  decoder has different markings than "ZXMC 3A16 0406".
