[Deadly Sones]

Good afternoon

Can anyone please tell me exactly what diode(s) belong in location D510 and 511? The 494 is making drive waves... but nothing on the gates of the transistors. Went to look at the driver transistors and noticed these 2 have been removed from the board.

Thanks in advance!!

Assuming that they connect base to emitter on the transistors, they were likely 1N4148s. Similar to attached.

I was just about to post that, they are indeed connected between the base and emitter. Thanks Perry!
