TS-850 CAR-board restoration
Yesterday I’ve swapped the capacitors of my TS-850 CAR-board. It was not a very difficult job, but men, what are those smd-parts tiny! I have to get another iron for this little stuff.
Anyway, the leaking capacitors are replaced. No damage to the circuit board underneath the capacitors was discovered. Only the green layer was damaged around the capacitors. I’ve scraped everything clean and then cleaned it with some alcohol. Next I put down some transparant nail varnish to protect the clean board. After reconnect it in the rig, it turn out to work fine! So job done I guess!
After I took the picture, I’ve swapped the 47 µF/16V one for a normal (not smd) version of 25V. There was enough room for it, so why bother to get the smd-version. Hopefully no leakage on my CAR-board anymore!

Hello!
I have fixed about a dozen 850s with this problem over the last 4 years or so. It is a MUST to replace them, even if they seem not leaking; all do or will do!. So, well done on your side
There are other typical faults which you can prevent with little work. In my WEB you have the info:

Hi Jose!
Really cool you’ve posted a message. You see, it was your site I’ve used as a manual when I replaced the capacitors. So you’re already in my bookmarks!
