Hi Klint.
First, don't turn on anything to see that it works. You could damage them even further. From the pictures the capacitors are u/s. These would all need to be replaced. All resisters/ coils need checking to see if they are correct or not open circuit. There are parts lists for all the Collins models you have listed. Valves are also available.
You have a big job ahead of you and there are many in CCA who can help. Email me for further help and who I can direct you to.
