Anyone Besides Yaesu Replace Finals?
|
aa8gk
Well, for as much as I spent on the 817, I got only ONE CW QSO out of
it! I'm mad as a hornet. And, no, I've made NO mods or otherwise abused the rig. So, I e-mailed Yaesu asking for a quote on repairs. Here's what they're sticking: P/N CB1152001 PA UNIT $266.97 EACH, IN-STOCK P/N CB1333001 FINAL UNIT 43.88 EACH, IN STOCK And, this isn't including the labor! Does anyone know of any reputable place that can do the job? 72 N QRT, DE AA8GK P.S., I may have a great little portable MF-UHF Yaesu receiver for sale here soon! |

replacement boards are disgusting. That brings another question, to anyone who ever had the finals go. Does the PWB (or other components) burn, typically, when the finals go? i.e: is there really a need to replace the entire PWB assembly, or could the power devices themselves be replaced? I would understand Yaesu not wanting to bother replacing the devices themselves, because the board probably would need to be tuned for optimum performance on all the bands, and they may not have the expertise and/or equipment to do that in the US, but considering the price of the board, if it were me, I would not mind saving a bundle by replacing the devices themselves, even if I loose a little bit of power on the higher bands. Of course, if the PWB is fried, that's not an option. Didier/KO4BB ----- Original Message -----

There are a few things to test before and after replacing the finals. This
testing should be done to determine if the finals, or an earlier stage, are at fault, and to ascertain the correct bias and drive levels of the new finals, as well as determining that all is ok with the rest of the radio, so that the parts replaced will enjoy a LONGER life.--Yes, you can just replace the final board without checking anything, and if you are lucky, it will work, but why not try to reduce chances that you will replace the wrong thing, or that the problem will recur?-----73, KC3VO--Bob. |

Replacing FT817 finals is pretty easy - screwdriver, soldering-iron,
multimeter. In the FILES section, have a look in the "Technicalities and Repairs" and "Repairs" folders for detailed instructions. You only need to buy the Final Unit. People have replaced just the Final FETs, but it is much more difficult and not much cheaper. The only alignment required in either case, is to set the Idle Current.

Sadly, because stoopid here hasn't used the rig since I got it last
year. The darn thing sat in a box. I should know better: my philosophy is 'use and abuse' something while it is under warranty - if it makes it past that date, you should be okay. Even so, how darn many CBs are there out there that have been pumping 5 watts (or close to it) into poorly matched antennas for years? I spoke with a tech at Yaesu yesterday who was very nice and said he had no idea why they had the influx of rigs needing the repair. He speculated Yaesu had purchased a bad batch of transistors, but added that they were not able to cause the finals to fail under laboratory conditions. I guess the good news is, he said that once the burned out finals were replaced with the new ones, the repair seemed to take hold and no such radios came back to the factory a second time. --- In FT817@..., "cleskie" <cleskie@y...> wrote: If you only got one QSO from the rig and you know it to beunmodified, I assume it is new.out of repairs.it!

Veenstra, Lester
I have some of the new transistors ( BTW Infinite VSWR protected), the RD07MVS1, and am in the process of getting ready to replace the old one's on a failed board (CB1333001 FINAL UNIT 43.88 EACH) that I have.

I'm curious about all these final failures. How are you guys using
the rigs? Are you using those "toys" like the "One Big Punch" or something? But then again, if that were a problem, I'd expect them to go up in smoke with every digital transmission. Because my 817 is my only rig, it gets moved around a lot, and BANGED around a lot, and I frequently fail to switch to the rear connector when I go mobile, until a couple calls, then sheepishly go switch it, switch the meter to power, and check to see if I still have any power. I must be living a charmed life, because after probably 10 instances of unterminated transmission, in FM, and a couple of those not at 500mw, mine's still going strong. I just keep hearing about all these problems, and mine remains ever faithful. At the least, I want to avoid whatever people are doing to them, as if mine goes, I'll be QRT until (and it appears, unless) I get another job. |

back half of the radio, switched harmonic filters and all. I made the mistake of asking the Vertex-Stndard folks for the amplier price and was also shocked, but it's not as if I'd asked for a light bulb. Forty dollars for the PA transistor board is, by the way, a reasonable price, and kudos to the designers for making that repair possible; the FET package isn't meant to be resoldered with a pencil- type soldering iron. By the way, price your car in terms of replacing it part by part, some time. You could make a living buying cars retail, dissambling them, and selling the pieces. (You make MORE if you just steal them and run 'em through a clandestine chop shop -- a common practice.) Cheers, Cortland --- In FT817@..., Larry Johnson <larryj@t...> wrote:

There's been a lot of speculation why the 817 PA's go, and I cling to mine; those power FET's were new technolgy, and the reliability wasn't all that it could be. Nowadays, I see, they use a different part. Failure analysis is a well-paid engineering specialty, at firms who need to do it. Cortland --- In FT817@..., "aa8gk" <aa8gk@y...> wrote:

BELIEVE ME, no one babys his rigs like I do! I've been hamming for 20
years and never blew a final on anything! In fact, I was a bit skeptical about all of these blown final claims. But, there does appear to be a problem. With any luck, your rig was manufactured after the last of the defective (?) finals were used up at the Yaesu factory. Sounds like after everything you've put your rig through, you're gonna be okay! 72 Pete --- In FT817@..., "n9hmg" <n9hmg@y...> wrote: I'm curious about all these final failures.

Hi all
My 817 stopped txing a few weeks ago. I took it back to walters & stantons The warranty is a 2 year as standard. I put it in for repair 26/6/03 and collected it today (15 days). I would have prefered it if the finals had not gone but am very pleased with the no quibbles repair, am hopeful these final will stay the pace. I don't know what caused the problem it has been on the lowest power setting connected to a ringo and used for packet for the last 8 or 9 months, the battery was disconnected. It was working at 5:30 am but not at 7am. The repair sheet just said finals replaced. Have Fun Dick m0clz --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system ().

Very interesting! We went through a long drawn out
thread here on the list a while back that was exactly about what you experienced. As I recall, several people complained that their 817's finals died after the radio had been stored away with the batteries still installed. Some felt that the rig was keying up and transmitting while in the box when the voltage dropped to the point where the microprocessor got confused and keyed up the rig. Others felt that the finals started conducting when their bias voltage dropped. I guess either one could cook your finals.
