Wiring points for?
I see blown open traces on the back of the board, attempted repairs, and lots of possible shorts.
If you could clean up that area so we can get a good look it would help.

Coming soon clean board. Best I can do. Looks to be a lost cause? I have repaired these boards with clippings before, lots of work. I needed a reference picture of solder points and wire positions. What's your prognosis ?
Been stored in a closet for 35 years. Thank you. Bought in 1984.

To me looks like it was stored in a damp room

I had posted a few pics of my 2000 here

Mine has also had some work, but for the most part it is in tact. There is a small coax for a receive amp that has been added, and around the PLL has been changed and a few thing removed, but I think some of the areas you are looking at are in tact.
If I can help with any more, let me know.
Looks like a project and a half, but it's all a labor of love.

Looks to me as if what you're seeing is also the result of incompetent repairs done in the past.

Any time a motor vehicle spends enough time under water, it will be considered "totaled" and no longer worth the sum total repair labor and materials needed to restore it.

Judging by your photos, this radio has crossed the line beyond "repair" and will require a "restore" job before you can use it in a reliable way.

Prolonged exposure to high humidity and moisture will cause hidden damage in addition to the oxidation damage you can see.

A radio that almost works, or is "weak" on receive, transmit or both is what we usually see from radios in this condition, once you get it to work at all. Fixing each and every fault that this introduces will add up to a laundry list of tasks.

Do you have tools for this kind of repair? A signal source for receiver troubleshooting, a wattmeter and dummy load? Multimeter? Or an oscilloscope?

It may be a lost cause? The work done on this radio was done by a respected radio repair and Mod person who no longer works on radios.
This is a realative of mine radio,first time covers been off.
This work is nasty, well THANK YOU for the pics, going to access the damages and make a decision. Will update with pics, if I decide to attempt this so called project?
Yes, I have the equipment even a signal Tracer, but going to possibly think about getting into a mountain of issues. May give it the Ole Labor of Love or Labor of NOT.

Need to add one more thing, if I decide to repair this, I may give it a try. I will look it over and look at the solder point and wiring. If I do, wish me luck. May give it the Ole college try. And thank a bunch for all of those who posted their pictures. Awesome pics, will work fantastic
Keep you all posted next week. Have a great weekend.
