Agree. Speed is out, but hey Peter still does an awesome job of showing and explaining the bench tech and procedures, so a little speed glitch is definitely forgiven. 🙂
Peter your the best and love to learn from you and this time your voice was very fast I think you recorded this in 10x or double your normal voice. otherwise a great job as usual. This is one of the best and favorite channel. thanks Mike
If you excuse me as I have a great respect for you and your knowledge, I’d give you a suggestion for those touchy trimmers. Use a screwdriver with a thicker handle or make your own (like a T for example). This will help you as you can control the angolar speed with your tangential speed of rotation. Thanks for running your channel, we all learn a lot from you. Best wishes, Diego
I had a PA transistor fail on the very first day of ownership with my FTDX101MP, although the rig had a warranty I do accept that I accidentally drove it too hard on FT8. (I had set levels but had done a reset afterwards). I changed the VRF150s without removing the board from the chassis. I bought the replacement transistors from Mouser, approximately £120 for the pair including tax. The radio has operated for over 4000 hours since without incident. 73
did same thing with an older ft101mp finals were over 200 dollars and within 10 seconds one of the new finals blew. dont know why but wasnt going to waste 200 more dollars on new finals again. it sat on the shelf and never worked on it again
Shouldn't the heat spreader plate be made of copper? It looks aluminum. 100 watts is a lot to dissipate. Not sure about a bad batch of transistors but you can tell the original ones have been cooking hot. The glue is all brown and discolored. It is not age, these radios not out long enough. Good video as always.
Copper or aluminum is always a discussion. I prefer aluminum, as long the heat sink is calculated in the right way. The downside of copper is that it is oxidizing.

Well the issue is if you see some repairs on a particular radio one can think there is a problem with the product but be assured it is not. To correct those issues, that's what warranty is for. It is a very good radio, superb receiver and good working noise cancelation features.
@@TRXLab I have FTDX10 and FT-710 for over year without problems. I am considering FTDX101D (when price drops) but repair issues give me pause ; ) Thank You.
I don't see how on a sofisticated radio like this, one final transistor could be demaged. Except if the bias potentiometers are faulty and jumping all over the place. Very risky that you didn't change them.
When you first started the 101 after replacing the PA transistors it seems to me that.... displayed the "channel" frequency of digital emissions in the 10m band :-))) hence my exclusively.... conjecture ? . Warm greetings & Best 73 ! @@TRXLab
@@TRXLab but sorry, mine are broken now after 4 years, why? without any reason, while a friend of mine after 1 year must be a big game of defective endings, in my opinion there is something in the system that is not perfect
Guter Tag. Ich habe eine Frage. Könnten Sie bitte ein Video von einem Netzteil machen? Überspannungsschutz. Es gibt etwas im Internet, aber ohne Erklärung und was sie verwenden. vielleicht eine Idee. Naar Nederlands goede dag. Ik heb een vraag. kunt u eens een filmpje maken van een voeding. overvolt beveiliging. Er is op internet wel wat te vinden maar niet met uitleg en wat ze gebruiken. mischien een idee.
Too much coffee mode LOL . I had to slow it down a bit to 0.75 and it was still a lil bit fast .......... Great job Peter ....
Had to set Playback to 0.75... Very pleasant video and as usual I learned more. Thank you sir!
AKA: Peter does 10 X on the coffee prior to the video!
😂
Peter is going to stroke mode
I have one word......decaf. excellent video as always.
Video speed is fast
😅
I had to double-check my playback setting. Peter like the speed just fine, and I can slow it down when you cover the fine details 👍
Love the videos but warpdrive is a bit tricky - this is overclocked!
Great video I put it on one half speed 0.5 and enjoyed it twice as much
0.75 is perfect.
I wish i had you as a bud. Your great at this .
Luckily, in youtube you can adjust the speed of the videos. Thanks Peter for the interesting repair!
Peter, of course we always learn in your videos ! Thanks for keeping posting !
Appreciate the new video Peter. Always looking forward to the next one. 73
I turned your speed down to .75
Thanks for the video 😊
I couldn't figure out how to slow the video down and got a bit stressed but finished it. I like Peter at normal speed:). Thanks, 73

Nothing to excuse any true comments, and suggestions are always welcome.
Playback at .75 speed made Peter sound normal.
Peter, 1.25x is enough for me with normal speed.
Great job on the repair. Regards from Romania
Yet another great video by Peter & Olaf ... 73s de DL6RDE/AA1KD, Charlie
見ていて楽しいです。ありがとうございます。😊
Lot of coffee today??? Great job as usual... Keep em coming. 73 de WD8JM
I like the new speed. Nice job as always.
😂
Nice work, very professional..
Well done, as always!
Superb. Subscribed.
Adjusting the playback speed to 0.7x makes it more comfortable to watch
I like the warp drive , maybe just a tad too much but a great idea.
You are excellent 👍

Yes, digi modes is one of the final killers and it happens very quick...
Thankyoufortheveryinterestingvideo.
there is realy no need to speed up the video, the natural sound of you are much better :-)
Hi yes I also had the play back problem it made it very hard to follow lol...
Fastes repair ever :)
Hi Peter another challenge for you it hasn't met the master yet trust you are keeping well
Thank you Peter for another outstanding video and repair. DId you use the VRF150MP matched pair version or the standard VRF150?
They came from Yaesu and the radio has an independent bias control for both transistors...
Hi Peter, I needed to reduce playback speed to 0.75X to view correctly 😊
I usually view videos at 1.25 speed but this time I was greeted by the Chipmunks. 😊
Gut geflickt!
thank you
Have nice Day Peter 73😅
Hi Peter, great work, great advice, great video. Can you recommend low temperature solder, pls! tnx es 73 de bemi, db3mi
ChipQuick have low melting solder with different temperatures...
did same thing with an older ft101mp finals were over 200 dollars and within 10 seconds one of the new finals blew. dont know why but wasnt going to waste 200 more dollars on new finals again. it sat on the shelf and never worked on it again
Important is to check if the bias pots are okay.
I think he has been drinking Seaport extra dark roast Cajun coffee ☕. It's the coffee that dissolve styrofoam cups. LoL. 73 Earnest K5EWM.
What's wrong with the playback speed?
yup, 0.75 is the perfect playback speed.
Play it at 0.75 speed. Much better 😂
Sounds like the sound is X1speed

Team x0.75, but still too much coffee... 😆
I have watched many of your videos, wondering why number 290 has speed ed up audio.
you can adjust play back speed so that it fits to your preferences

Very risky that you didn't change them.
The pots are something we always test, you are right that is essential. In this case, the potentiometers were fine.
what supplier did you purchase the transistors?
It is said the transistors were purchased from Yaesu.
I have a kenwood tm741a, I could use some help?
Congratulations on another successful repair 👍👍👏👏👏👏,
By the way someone fried the PA in this super TRX with a stupid FT8 on 10m 👎👎🤦♂🤦♂.
yes, that is one explanation but unfortunate not proved..

Where'd you get the stuff ?
from Yaesu
It's an OLD joke,,, when somebody appears drugged up,,,, because the video is so fast.... " where'd ya get the stuff?" :)@@TRXLab
Peter. Ich hoffe es war nur ein Versehen den Videospeed zu erhöhen.
Speed use 73
I trought I was drunk
I got puffed out watching it..
heute hat er es eilig ;-)
I think play speed is wrong! I put my play speed to 0.70 which sounds better.
me too
The video is playing at x2 speed I think
no
Sound speed too fast??
I do not like the higher playback speed. Even cutting it down to .75x on youtube, it’s still on the fast side.
0,5 but sounds strange anyway
ok
Peter did you take extra medication today
lol
I think, you know, obviously there is something wrong with Peters output power.
he had to much coffee
sorry because the power amplifiers break, there are several ft101mp radios with this problem, why?
As far we have heard, there was a bad batch of transistors in the first run. What we can confirm is that by now different types gets delivered.

may be like my video #99?
Couldn't watch this due to audio speed.....No option on my tablet to reduce video speed 😮
hm, should available at tablets
Hallo Peter Video läuft zu schnell 😂
ein bisschen mit YT speed adjust nachreglen :-)
Lol 😂
Really?
No need to remove the PA board for this repair,I never do.
As I said the result counts
lol

Hi Peter slow down a bit this isn't like you
