i am ready to replace my transistors to attempt a main board repair, was hoping i could figure out which head was powered by which transistors in the service manual but i had no luck.

question #1. which print head is "Head 0" and which print head is "head 1"? i Need to replace my Yel/Mag transistors.

question #2. which group of these transistors in my pic is for the yel/mag print head?

thank you signs101!
