Hallo Peter, wieder eine tolle Arbeit bei deinen Reparaturarbeiten. Meine TS-50s schafften locker 180W-PEP. Um ein Überhitzen der Finals zu vermeiden, habe ich den Lüfter im Standby-Modus mit niedrigen Drehzahlen drehen lassen und mit steigender Temperatur während des Sendens mit höherer Geschwindigkeit betrieben. Diese Radios waren solide gebaut, um lange zu halten, aber viele von ihnen hatten Kühlkörperprobleme, selbst wenn sie vom Eigentümer nicht berührt / nicht modifiziert wurden. Schönen Sonntag & 73
On my TS-50 I had the very same problem - an oscillating audio amplifier. After replacing all the electrolytic caps, the fault persisted. Eventually I soldered a 100 nF cap parallel to C124, that cured that nasty sound. Since then, it works like a charm.
Nice exorcism of the evil crapacitors, causing the zombified victim to howl in pain. Really enjoyed the video Peter! The TS-50 is a brilliant radio and I wish I had not sold mine.
Hello Peter, again a great job on your repair work. My TS-50s did easily 180W-PEP. To prevent from overheating finals I made the Fan spinning on low rpms during standby mode and running higher speed with rising temperature while tx. Those radios were solid built to last but many of them had heatsink porblems even untouched / unmodified by the Owner. Happy sunday & 73 de Your Friend Uncle Guenter

Those electro SMD Caps do NOT hold up like the older caps back in the 70's , 80's and even the early 90's caps.... SMD's were getting really popular when I got out of the business in 1998........I buy Nichicon and Rubicon caps only , If I can use a old style cap and cut the leads short , then bend them sideways close to the board I will do that , MORE life from the cap like that .... GREAT video as always Mon Ami .....
Hi Peter, after 33 secs of this vid I wanted to make this reaction. Whatever comes next, this one is epic already. You opening the vid with your enthusiasm with a look to you it being a kind schoolboy naughtyness, saying that this Kenwood having problems of getting turned on, well, EPIC!!! Have a great day :), enjoy winter over there in Austria. Greetings from the Netherlands!
Those SMD electrolytics are a real pain and cause all sorts of issues with older electronics. Very neat job Peter. It must have been difficult to get them out with all those plastic connectors so close. How did you remove them? All the best Graham

Danke für den Rat. Wie heißt es doch so trefflich: "Vorbeugen ist besser als heilen". Habe übrigens die Speicherbatterie auch schon wechseln müssen.

Oscillation in the audio power amp? Haven't watched all yet, but this springs to mind immediately :) I changed more than 20 SMD lytics in a TS50 some days ago. Tracks around the one on the front panel had to be repaired also
As usual, nicely presented video from Peter. However I'm not sure that leaving the TX power about 50% higher than max is acceptable - I hope the owner was told about this in case he was unaware and later on cooked his finals because it was left set far too high. I feel there is a degree of responsibility with the technician to set important things to be as they should - if this rig had been mine I would have been grateful for it to be reset to the factory limit in case it ended up fried because I hadn't been told of its excess wattage.... I wonder what the TX signal was like for harmonics with the settings at 150% of design max... No ham known to me would run a rig set like this, we'd all be happier by far to have factory settings restored to a rig of unknown history - these are super little rigs when in fair order, but they're getting nearer the grave with every year that passes!
That's why it's good to know something about electronics because of something breaks you can probably more than likely fix it yourself and fix other people's electronics too I have a flat screen TV that I haven't gotten around to fixing yet because I've been so busy and haven't gotten around to buy a replacement parts from I tested and troubleshot the board and it's shorts all over that board to the point to where I said forget it I'll just order another motherboard but I haven't gotten around to doing it yet
cool video,and you even give people the room to diagnose in a way... very cool!! bought a ts 50 myself and when you switch in vfo a and activate the up button it jumps to vfo b,is this a known fault??? cool video love it..
Years ago, troubleshooting the failures of AM broadcast receivers, this symptom was called "motorboating" - and the first suspect was the power supply filter capacitor...
Hi Peter. really enjoy watching and learning from your videos. Working on a TS50 myself and totally confused with it. Have no receive audio. Getting beeps through the speaker as buttons are pushed, and volume is working but RX not coming through. Any chance you have come across this before? I would love to know what the red led is at IC11 on the TXRX board! Cant find anything on it. Stay safe.
Hi Peter, thanks for the video. A simple question: my lithium battery is gone (unfortunately here in Africa I had to order it). Do you think that the power output is related to the protection done by the lithium battery? The radio doesn't give any output power and it has been in standby for sometime hence the Li-on battery gone. Thanks
It reminded me of a toy steering wheel with mechanical rolling road. There's a few vids of the "Tomy Racing Turbo" and someone has also put a Pi & LCD dashboard in to play Outrun. 🚘
Hopefully you told the owner that his rig is in jeopardy because of the high RF output is too high by 50%...he/she may not know that and may want you to see why it's power level is so high. Hate those darn caps in the TS-50! ;-)
Hello Peter, missed some videos because lake of time but te gets up now. Always good, love it. I think using uv ligt is handy to see if there is an leaking capacitor. But your method is new for me but smart and simple! Thanks Ps. Do you use 10MHz reference on the cms? I just installed it but have to find out how to know if unit is using it or the internal one.
Hi Peter, at 27:03 point in the video there is a perfboard in the bottom left corner with an IC that looks like add on or some kind of repair. Do you know what is this? Doesn't seem a factory element. 73, Pablo
i would have turned the power down to spec. and tell the OP its the best for the radio and if you want higher power get a small external amp. hihi great video
Thanks for all your videos!! Great work!. I have a question about the outgoing lowpass filters. If you run the radio without them, What would happen? Are they just to protect for unwanted outgoing interference or do the protect the finals too?
yes, simply because all data sheets today are using 120 Hz for testing. I have several videos on electrolytics here on my channel such as video #83...you may have a look around..
The circuit diagram (12:19) doesn't make sense... Pin 7 is a bootstrap pin according to data sheet and appears to be decoupled to ground by C126 22uf. Surely a value this great would be shunting any audio from pin 6 by C125 47uf and have a very hard time??
Hello Peter, I have to change the leak capacitor on display unit and ask you for your cleaning procedure of the acid on the print. What do you use therfore? Liebe Grüße Mario 73 de OE6FFF
Hi Mario, very often you have to sand off the board clean it with isopropanol alcohol and than you need to put fresh green uv solder mask to the pcb,,, hope that helps.. 73

Would have liked to know who made those faulty capacitors. My bet they were not Nichicon or Panasonic brand.
hard to say but it is not Kenwood's fault. Back in the time there was a huge legal issue with the formula of the electrolyte...

i would have turned the power down to spec. and tell the OP its the best for the radio and if you want higher power get a small external amp. hihi great video
We always have the same reflex but you can't do it simply because it is not your radio..
great overhaul ! love it
Thank you!
Thanks for all your videos!! Great work!. I have a question about the outgoing
lowpass filters. If you run the radio without them, What would happen? Are they just to protect for unwanted outgoing interference or do the protect the finals too?
The filter is a so called harmonic filter set to reduce unwanted frequency on the bands. It is regulated by laws that you have to use it.
So cute radio! All I learned from this video is all those electrolytic cap's should be replaced.
correct
Hello! I gave you a big like for the nice enthusiastic attitude at the start of the video! :) 73! YO9IER.
thank you
Great video thanks
Hey Peter do you play golf? If so, what percentage of the time do you get hole in ones!
Great work professor!
lol I know what you mean and let me answer it this way. If you are Tiger Woods your percentage might be a bit higher..
@@TRXLab I think you're the new Tiger Woods!
Hello Peter, can you explain why you test the capacitor at 120Hz?
regards
yes, simply because all data sheets today are using 120 Hz for testing. I have several videos on electrolytics here on my channel such as video #83...you may have a look around..
The circuit diagram (12:19) doesn't make sense... Pin 7 is a bootstrap pin according to data sheet and appears to be decoupled to ground by C126 22uf. Surely a value this great would be shunting any audio from pin 6 by C125 47uf and have a very hard time??
Hello Peter,
I have to change the leak capacitor on display unit and ask you for your cleaning procedure of the acid on the print.
What do you use therfore?
Liebe Grüße Mario 73 de OE6FFF
Hi Mario, very often you have to sand off the board clean it with isopropanol alcohol and than you need to put fresh green uv solder mask to the pcb,,,
hope that helps.. 73
Peter, at the 27:05 mark, what is the little tiny circuit board with the I.C. on it for? Just curious. Thanks
it is a mod but I don't know what it is doing
very good nice job .
Thank you
What's the name and model of your PCB Holder?
pcb holder for mobile phone repair from china..
@@TRXLab - Thanks
Are there any common failures to look for on the Kenwood TS-2000 radios other than the 455 kHz filters?
other than the filters in the early models not really but that does not mean that a lot of ts 2000 get not fried ...
What is your callsing
Great resurrection! How much is the rated power for TS-50?
Thank you...100Watt
So, what is the "crazy" part of the fault?, I mean, caps is the most usual failure, so, what I miss?.
Wie immer perfekt ausgeführte Reparatur.
Der Drang mir den Bereich um genau diese Kondensatoren anzusehen wird wird immer zwanghafter 😵 jetzt weiß ich wieder mal warum 🤓

lol ja sollte man tatsächlich machen.. 73
I have also fixed several TS-50S with same/similar problem. ALWAYS the capacitors have leaked badly. ALL TS-50S are a TIMEBOMB. They WILL fail. For sure
Yeah that is true
Without watching any further than 1:40 I will take a guess that it is a shorted electrolytic in the audio circuit.
Start of video, my hunch bad cap, amp section...c127 leaking eletrolyte,also c126 has been poop 'ing on board.
perfect
And one way you can tell when you have a bad capacitor is when they swell
most of the time you can't see it
Its a radio there is nothing complicated inside.
If it's a Kenwood to
😃👍
Danke Ulrich, hier darf man auch deutsch schreiben.. ;>)
And by looking at that board you can tell it had burnt out all over the circuit board with bad capacitors
very seldom what you describe..
The older one
Interest malfunction, like!
hm not sure what you mean?
Das deutsche OM schon immer einen Waffel hatten merkt man hier immer wieder
I would like to have the knowledge of Peter... he is a genius ... best 73s de DL6RDE / AA1KD, Charlie Merscher
Thank you Charlie but no Genius here only an old man with a little experience..
