Pete, thanks for the report and the images.

About the images.

Can you try to read any numbers or letters on:

Q1, Q2, Q3
D1 & D2

The numbers and letters on each device will likely be 3 characters

(such as 3F4, or something similar)

About the TZJ (cannot read for sure? it's above Q2),

Does it look like a diode?

And, TZ2 or T22 near the input connector, does it look like a diode? could be a transient protector?

Q4 and Q5, fairly sure they are regulators. Are they leaded components, like TO-92, TO-93 cases? If so, do you see any nomeclature?

A small flashlight and magnifying glass can be very helpful, also try lighting from different angles.
