Thanks for this. An Eagle ended up on my bench with exactly the same symptoms. Followed your troubleshooting procedure, bought replacement transistors, installed and adjusted bias as you recommended. The owner is very happy to have a rig that he can put on the air again.
I stumbled onto this chanel one day a couple months back when I was out looking for a new multimeter. I've been hooked ever since. I've learned so much in just a short time, its very addicting. There at the end of the video, when he raised his hand, I almost expected him to say; "Live long, and prosper," with his fingers split . These tips may come in handy in the near future. Thanks a million !
You're an EXCELLENT technician. I was a tv repair tech for 35 yr, of course that business became a throwaway business. However, I've learned more from your videos in the past couple of months, I wish I had discovered more RUclips channels like yours years ago, although, info like this wasn't so available yrs ago.. Great work and hope you will continue giving us your knowledge and Quality information.

I wish I would have found this long ago, very good information from Paul, one heck of a sharp guy, wish I had half of the test gear he has, his video got me back going, started restoring some of my old stuff.
Thank you so much for providing such an excellent troubleshooting video. I had a Ten Tec Orion that had zero output. Using this video I was able to troubleshoot my PA section. What I found was the problem was NOT the final transistors as this unit had. But instead it was the driver transistors that were Dead. Replaced both and rig was back to 100W out! Cost was less than what it would have cost to ship the rig to Ten Tec for a repair. THANK YOU!!!! Could not have done it with out this Video. 73 Jon
You are the first person I've seen that explains signal path through the various components and tell why and what they are for. This is the best and I've been looking for years for someone who does this. Much much thanks.
"Some people(my wife)" say that I am smart, but you are on the level I would consider smart. I appreciate how clear you come across, thank you. I watch your entire videos without yawning, not bad.Your videos gives me hope that some day I too will think this clearly but if I never do at least I know there are others like you who can. Good job.
You are a great systematic diagnostician which I appreciate very much. Everyone seems to want someone else to give them all of the answers, without giving a process any thought. Continue to challenge the minds of our day with interesting and detailed processes. Thanks.
I have watched a few of your videos and they are so well done I have become addicted. You have an excellent instructional delivery. It doesn't even matter if I have the device you are working on-you impart very important logical service techniques as well as emphasizing safety. High ratings for filming presentation, clear audio, technical advice and especially full guidance and not assuming what or what not the viewer already knows. Thank you.
Love your channel... in the 70's I did lots repairs. All Neighbors use to drop their stuff off of my did the repairs. I never I came close to have the knowledge you have. As I got older into the 1980 I moved away from it.. truely forgot so much.. I do some repair Like on my TV's . God I love your videos so much I never do so much I think I might have known so much I wish I would have known and are things I do know you are fantastic your voice is perfect for the videos I've been watching and won every single evening's thank you
I use the AM mode with no audio to do most testing and antenna tuning. Most solid state radios automatically reduce the carrier level to a MUCH safer level than FM or CW. With 1/4 the carrier, it's (nearly) impossible to burn out the finals with a mismatched load. Thanks for another outstanding video!
Mr.Carlson I watched yesterday late down at night your job of repairing Yaesu 1000 . I think it was model “D” Have to say it is very impressive. I love your shop equipment. The way you approach and evaluate unpredictable chaos behind the back cover of the radio . I was impressed of your idea to replace whole PC board and install new larger antennas switching relays. You presented to me and many other hams not just ability to find and fix the problem but a higher CLASS of electronic experts .This days it is a problem to find a reliable electronic shop. I also owner of Yaesu 1200 transceiver .Thank you and good luck!
Thank you for your response to my email. Can you recommend someone to work on the radio? I am finding it impossible to find someone to fix it for me. Thank you. John
Wish I had found this long before You sir are so good and Have hooked me watching and learning you make look so simple with knowledge you have Thank you
I enjoy watching your videos so much I go back and watch them again lol it never gets old and things that I didn't see before jump out at me the next time I watch. Lotta a great information your providing.
Lesson learnt! Before switching ON connect it to dummy and turn power knob to minimum... as you never know if crazy processor is confusing or what... Thanks!
Thanks for all the work you do in explaining the shop techniques. Wish I had all the test equipment you use. The explanations are clear. Great job of teaching. Makes me wonder the path you walked to get to this stage.
Hey Paul, great video and excellent explained and presented! Nice curve tracer. Would be good to be able to check the transit frequency as well... A big thanks for the kind mention and the link!!
+TRXBench Any time bud! We geeky "techy" type guys gotta stick together...LOL! I agree, testing the Unity Gain Frequency ( fT ) would be interesting on the fake devices. I wonder how far they would get?? Hmmmm, Maybe a future video. Output admittance ( hoe) and breakdown looked much the same (off camera)
Once again, this repair demonstrates the presenter's incredible depth of experience. This has allowed him to develop the most valueable of debugging tools ... his intuition. One recommendation. "Solder" is pronounced 'sod-er'. The 'l' isnt pronounced in the US.
What a great clip. Though I don't understand most of what you did I still enjoyed it. I sure wish you were my neighbor, I could fix you up with at least four maybe five radios I need fixed.
Very interesting, nice that you take the time to explain what you think, and show us the schematics, so that amateurs like me is able to learn from the video. Like always, nice sound, video quality and lighting. Keep up the good work. Greatings. Morten (Denmark) :-)
Very good video. I'm no electronics repair person, but very fasinated by it. I'm attempting to repair my Astron RS-35M aftter watching you work on the model without the meters. Mine won't handle more than 21 amps. My Yaesu FTDX 3000 pulls 24 amp in FM mode and when you key the mic the radio shuts off like a bad wire connection. I've cleaned all the connections inside and out of the power supply. Oh by the way the power supply is 25 years old now.
Another great repair video. Thanks. I am going to order a couple of those 2782 for my Kenwood TS2000. One of the C5125 has a B/E short. Should be an easy fix. Thanks again for the video.
I enjoyed your video very much. Great Job!!!! My only suggestion would have been to verify the input signal to the base of the RF Finals after lifting the base lead to verify no issues existed in the coupling from the driver section to the RF amps. You verified a 55 volt signal at the end of the RF Cable from the driver, verified little base signal but assumed the cause of the low reading was due to the problem with the RF Output transistors .
Perhaps you didn't know it, but the test equipment Paul used is worth far above the cost of the old transceiver. MMMmm seen THIS before! And MY comment is after watching the video four years after it was made. Nothing has changed except the date. Still superb! de KQ2E
Hello. Came across a ssb walkie talkie, which I believe is from late 60’s, or early 70’s. It’s a single channel, “brick”, black steel case about the same size as a realistic trc-101, with the cover on. It’s a little over 5 megacycles, not sure yet most likely lower sideband only. It only has a tuning and volume control at the top, with battery/signal level meter and push down switch for battery level. I was able to charge the General Electric rechargeable battery pack in the rear. The ptt on the left, with antenna on top of the switch with a 259 female connector for a right angle antenna which is larger than a regular antenna. It’s possible it was made in the USA, has USA parts( parts inside radio parts larger than a normal walkie talkie, a speaker made in Japan, I’m not sure about Holland electrolytic capacitors where they were made, some rca transistors,usa mechanical filter, so not sure if it was made in Japan or not. It has an american company name that I can’t find any info of, or the model number of the radio.
I was hoping to see a short presentation of the two-transistor & balun "how does it work" output stage. I have seen probably one such presentation, but to really learn, I would need at least one repeat! I also believe I noticed ferrite beads on the two base resistors. A mentioning of them would also have benefited the presentation, if indeed they were ferrite beads what I saw. Otherwise, thank you for teaching a few things to an old DC & audio guy! (Well add to that switching power supplies...)
Great video. I paused and identified the four fakes ones pretty quick, but I went by the faded fonts and letter alignment - I didn't even notice the leads until you mentioned it lol. I've seen that letter fading on fake ICs as well. I've also seen counterfeit Panasonic and Nichicon electrolytics too, the silk screening is off or faded and the vent pattern on top doesn't match the real ones. Gotta be careful these days...
Yet again another superb vid. Mr. Carlson! Big thumbs up and I want more! :o) Thanks for the link to Peter as well. Will check his stuff out right away.
Hi Paul,Thanks for the tutorial in fault finding and repair,,I also like Peter's video's along with Alan W2AEW,I'm learning lots from all 3 of you. Paul M0BSW
I finally found the video again where you show your B&K curve tracer and wavetek HUGE monitor!!!! I bought the exact same setup after seeing this video....one day i will get around to setting it up LOL!! would really like more info on your set up. I know you mentioned you had modified the B&K
I like this. I just wished this radio company had not gone out of business I know this has nothing to with what you did. but I never got a chance to own one
I live where they were made and it was a sad day when they tore the factory down. The guys that run it were awsome you could go there and get anything radio related and every year they had a ham fest in there front lawn.
Once again, another fantastic and educational video. Thanks so much for sharing your skills. Your attention to detail on every aspect of the repair is amazing. I learn something new every time I watch. I would love to know more about the curve tracer you use. Make, model, etc. Had no idea there were fake transistors out there. Mitch - KB3GKC
+Mitchell Smith Hi Mitchell. Glad your enjoying the video's! The curve tracer is a B+K Precision model 501A. Unfortunately, the market is absolutely saturated with fakes right now..... Ic's as well! They are getting so good at it, it's really hard to tell the difference with many. Much of the time, it requires destructive investigation to see the difference (die size).
Thanks for this. An Eagle ended up on my bench with exactly the same symptoms. Followed your troubleshooting procedure, bought replacement transistors, installed and adjusted bias as you recommended. The owner is very happy to have a rig that he can put on the air again.

Hello, Mr. Carlson. Thank You for having us.
I have watched a few of your videos and they are so well done I have become addicted. You have an excellent instructional delivery. It doesn't even matter if I have the device you are working on-you impart very important logical service techniques as well as emphasizing safety. High ratings for filming presentation, clear audio, technical advice and especially full guidance and not assuming what or what not the viewer already knows. Thank you.
As usual Paul, you do a superb job of presenting these problems, troubleshooting techniques, and repairs. Thanks for all your hard work!
+Earl Richardet Thanks for your kind words Earl! See you at "larry's" soon :^)
I love the troubleshooting videos. Reminds me of my time in the Navy. Great job as always.

Great video! ...also, had to smile when the reflection of the screwdriver appeared when you adjusted the bias current.
As always, on the edge of my seat the whole time.
Thank you for sharing !
that radio looks incredibly friendly to work on. I love how each section is separated.
Thank you for sharing these videos. Its really refreshing to watch someone methodically solve problems like this.
FailedSquare , AND... correctly said, also!
I have a tube radio, it's old and had rodents urinate on it. I understand transistors but not tubes. You seem like a genius and a great teacher.
Mr.Carlson I watched yesterday late down at night your job of repairing Yaesu 1000 . I think it was model “D”
Have to say it is very impressive. I love your shop equipment. The way you approach and evaluate unpredictable chaos behind the back cover of the radio . I was impressed of your idea to replace whole PC

I was hoping you would test the knockoffs, and you did. It's really a treat to watch a true professional work especially one as thorough as you.
+wgenerotzky
Thanks for the kind words!
The way you explain everything is amazing.
I have a Yaesu FT900 I want you to fix. I will pay whatever you charge. You are the best I have ever seen !!!
Hi John. Thanks for your offer, at this time I'm too busy to take on radio gear.
Thank you for your response to my email. Can you recommend someone to work on the radio? I am finding it impossible to find someone to fix it for me. Thank you. John
Finals check w/ vom plus "identify the fake transistor" excellent video! Nice transistor checking link too! Thanx
Wish I had found this long before You sir are so good and Have hooked me watching and learning you make look so simple with knowledge you have Thank you
Thanks for your kind comment Mr. Elliott!
Your lab is cool. It reminds of old space station pics
Thanks!
I enjoy watching your videos so much I go back and watch them again lol it never gets old and things that I didn't see before jump out at me the next time I watch. Lotta a great information your providing.
+wade hicks
I'm glad your enjoying the video's Wade. I have been working on a radio project for quite some time now, that video will be coming soon.
As a radio ham this was very interested. I'm no expert but the Ten Tec looks like a really well made righ.
In the pictures on the sites of the stores you can see almost only fake transistors.
Great repair :-)
+smbrob The market is full of this sort of thing right now. Thanks for your comment!
Very well done video. Very good explanation. Especially about the fake finals !
Lesson learnt! Before switching ON connect it to dummy and turn power knob to minimum... as you never know if crazy processor is confusing or what... Thanks!
Mr. Carlson, you're very nice and and your explanations are very clear. Please continue with your video productions; I enjoy them very much.
Thanks Jeff!
You Are A Very Good Teacher Of The Field
Of Electronics !
Thanks Fernando!
Thanks Paul, I kinda feel like breaking it again just to watch the sequel.
+Toe Knee LOL, Glad you enjoyed!
Real precise in testing and trouble shooting the PA problem and driver stage on the rig! Thanks for the review.
+Dennis Petersen Glad you enjoyed Dennis!
Mr. Carlson demonstrates a knowledge based and disaplined approach to problem solving. Wish i could be half a Carlson !!
You very easily could be, just hang around. Thanks for the kind words Robert!
Thanks for all the work you do in explaining the shop techniques. Wish I had all the test equipment you use. The explanations are clear. Great job of teaching. Makes me wonder the path you walked to get to this stage.

Impressive work I am amazed by your skills are you a teacher or is it just a love of what you do?.
I have the same question.
What a great clip. Though I don't understand most of what you did I still enjoyed it. I sure wish you were my neighbor, I could fix you up with at least four maybe five radios I need fixed.
Now I know how to set the bias. Bootleg transistors. The clones looked real but they weren't, thanks for the fake information and what to look for.
Another great one, transistor curves wow!
