Maybe I’ll check those 2 diodes and the 300ohm resistor, but I’m sure
they’ll probably be ok.
The transistors and 300 ohm are inside the chip, you can see schematic of the
chip at:

That would certainly explain why I couldn’t find them. 😂

If you want to confirm the currents are OK another way is to measure voltage
drop across 47-ohm resistors R780 and R770. Schematic shows 100mV delta-V is
expected on these resistors.

Will do that and report back. Thank you.
