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

[RUBICONTJ]

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

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

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 :-)

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
