Kenwood TS-2000 Pre Amp HAM Radio Repair Part 2 of 2

Repair of a Kenwood TS-2000 at Communication House workshops, Kent, United Kingdom June 2011. I have put this video together to give insight into the work we carry out at Communication House.

The video is not meant as a tutorial however; I do hope that someone out may find it useful. Please feel free to ask questions and I will do my best to answer them. We have tried to keep the video as simple as possible due to time restraints.

Note:
Please do not try and repair equipment yourself unless you experienced to do so as this kind of equipment can be easily irreversibly damaged. Sadly I see this all the time so please think before undertaking repairs.

I hope you find the video interesting as we have enjoyed putting it together. Best Regards John

The test you showed at the end, is this how you initially diagnosed the switching transistor? Great work by the way, keep them coming!

@bbjunkie1023 Hi, Sorry for the delay in getting back to your comment. The test at the end with the voltage setting on the multimeter was to check that the DC switching was present for the preamp circuit.

I do have a number of vids with other radios I have repaired however; I need to find the time to edit them so they make some kind of sense.. Thanks for watching. Regards John

Glad to hear you enjoyed the video. Modern equipment needs to be handled in this way due to ESD effects as it is easy to induce faults by poor handling of PCBs etc. Best Regards John M0XFX

I’m happy that you find the videos interesting. I do enjoy repairing amateur equipment and I too am also a fan of the old tube gear. I recently sold all my Collins S line equipment :-( (Cried in my beer for a week HI). However; I do still have my trusty KW-2000B. I am lucky enough to know some of the engineers that used to work at KW back in the day. I do have a number of vids regarding repairs and as soon as I have the time I will post them. Thanks for watching. 73, John M0XFX

Maybe you can help me, my TS2000 is doing this, i thought I was supposed to replace Q705 2SK2569? You replaced Q706? with a 2SB1132-Q ?

Then I thought Q12 was the pre amo for the lower bands?

What am I missing so I can buy the correct parts

A great job! You seem to handle the radio like a surgeon. If ever my TS-2000 will develop a defect, I'll send it to you :-)
