#14 Kenwood TS 50   Capacitors and  previous repairs gone bad pa...



In this video we look at a tech special TS-50. What we find is smd caps have leaked on the pcb causing corrosion. Someone tried repairing with through hole caps but ended up ripping traces off the board. Part one I will evaluate the repair and remove parts then clean the board. In part 2 I will show you how to repair the missing traces the correct way,

I have added a few close up pics on my website using my cheap usb micro cam. Will be adding more pictures and info as the repair moves along?

    Really looking forward to seeing how the repairs go on this one. Could you talk some about why this happened and how to do the job of replacing these caps without causing damage to the board?

    Hi Buddy, really a shame what has happened to the radio. You are right saying you are fighting against two forces…. Hope that this job will not become a nightmare. Good luck! Take care my friend.

    I feel your pain. I did one of these a few months ago that was in similar condition. The one I had was also butchered on by someone trying to replace the caps with through hole caps. I was able to do the trace repair with conductive epoxy dispersed with a very fine syringe applicator tip. Good luck and have fun. 🙂

    Your video productions are getting better and better. If you get that radio working it will be a miracle. Your nomenclature of Radio Tech would then need to be changed to Radio god.

    Great series on the TS-50, you show how important is is to pull the schematics and use the basic meter (analog or digital) to take reading BEFORE diving into the rig to r/r parts.

    FYI

    An older android phone with camera makes a good usb camera, just hook it up and you can get great close up photos of the boards, not as great as a dedicated microscope but close enough to see what you are working on and good to find broken traces on the vintage gear.

    That is one of the worst attempts to fix a radio I have ever seen; the workmanship is appalling, an F grade is not low enough for this major botch. I can see why you were hoping to find a replacement board on eBay.

    I hope those caps in mine aren't going bad! Guess I'll have to take a look inside.

    I have trouble with the ATconections. Whwn I use it the TRX will be blocked on that band I am using for the moment and I must release the battery to get it work again.

    moral of the story: don't buy TS50. even if it's working, it will fail soon, with a hefty repair bill.
