Indeed... typical easily overlooked mistake.

It is possible that all D5 does is keep the standby light from staying on when the switch is flipped. And the standby switch being on the ground return might last a lot longer with so much less voltage across it than one on the HT. But I am curious. Removing D5 seems like it might mess with the bias. Any other worries?
