I still think this is TERRIBLE UI design. #macos

This is what the service manual gives:

Trying to get the PCB out of the radio. The service manual suggests it should just hinge up if you release two tabs, but I can't find the tabs.

Back at this radio. There's no significant voltage across the input to the DCDC converter. All there is before that is a pair of transistors a switch and a couple of switched jack sockets.
I've got the steady arm out for the camera as I've had a comment or two that my repair videos are a bit shaky. Fair enough.

Teddy had a trim yesterday. He's not quite so shaggy now. He'll look better in a week or so when he starts to grow out again. #dogsofmastodon

Having a first look at @doc's radio.
It's totally dead. Drawing a shade under 0.05mA I assume that is keeping some clock running or something, but nothing else causes any more current to be drawn.
This should be an interesting repair.

I should see if I can update the database on this. #wikipedia
