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!

New set: Kenwood TS-850

For years this radio has been my dream. I already did own a Kenwood TS-450SAT. A very nice radio. But the other day I saw a TS-850SAT on internet for sale. In the corner of the shack was a Icom 910H which I never used. I traded the Icom in for the Kenwood TS-850SAT. A pretty nice deal, I thought!

After close inspection it turn out the TS-850 has a serialnumber in the 20-million…. Bummer! That numbers turn out to have several leaking problems. But the salesman ensures me he checked the rig and there where no traces of leaking capacitors. He also gives me a 6 months of warranty. So with a good feeling I went home and plugged in my brand new TS-850. The rig performes excellent. Really cool features (e.a. slope tuning) and a good quiet receiver picked up at least twice as many station as my TS-450SAT does.
But now lift up the hood to check the dealer claims.

Hmmm, that doesn’t look very promising:

The capacitors of the CAR-board ARE leaking, let there be no confusion about that. Now I can do two things: bring back the TS-850SAT to the dealer to let it fix. But he already replied my e-mail with above picture saying: this is no proof, if you want it fixed, you have to pay half of the bill.
Well, I’m not want to pay anything since he promised me 6 months of warranty.
The other thing I can do is fix the problem myself. So I ordered the 10 capacitors of 10 µF/25V. I hope they arrive tonight. I will replace them immediately! The 47 µF-one wasn’t available so I have to search a little bit harder for that one. But before I order, I’ll inspect all boards for these faulty blue smd capacitors and replace these too.
