Re: Blown final club? I think I have a membership
I believe you are correct.
It makes sense that Yaesu is dropping support for the FT-817 (non-ND) due to age (meaning if one is sent in for repair, it will be returned unrepaired).
BUT, the question is, are these two board numbers from FT-817 or FT-818?
Final Unit and is number FR006000. Which mounts on top of the PA board, FR005190
It would also make sense to drop support for FT-817 specific parts, and I suspect those numbers are FT-817 specific, they are probably planning on stocking the FT-818 specific parts.
Interesting to see how this classic radio is being treated in its twilight years...
The FT-817 was released 23 years ago, the FT-817ND was released 20 years ago. The FT-818 was released about 6 years ago - I don't think Yaesu can drop support for the FT-818 yet... Ken, N2VIP? On Aug 5, 2024, at 19:19, Freyja Clark Turner <wa3jpg@...> wrote:

Dean,
Recent information leads me to believe that may not be true. It's only an initial report, but it seems FT-817 (non-ND) may no longer be supported, and Yaesu appears to be no longer interested in stocking/selling replacement finals boards for at least the early non-ND models.

So, I called Yaesu parts and ordered 3 PA boards. $26.00 each.
Problem is that they don't have any in stock. She took my order and credit card info. I received a email confirmation. They will ship when the backfill order is received.

Re: Blown final club? I think I have a membership
Hi Jeff.? I am very curious.? Have you done the reverse phase mod there in the final RF stage?? Had you checked and set the bias carefully?? I have been out of this loop for years, but I had one of the first run when finals were blowing and a few of us saw some design problems with the phase or the input to the final board.? I did all of that and have not had a failure (I am not claiming that my mod fixed any problem, but curious about others who DID do the mod and whether the finals released the blue smoke).?
My 817 still happy, only a few other repairs needed in the many years I've used her.? She is not used a whole lot these days, but I imagine I'll want to stock replacement PA transistors myself.?
Did Yaesu ever release a service bulletin on this?? I know that the 817ND made some changes, just not sure what those were.

On first blush, that appears to be an excessively high mortality
rate. Any thoughts on "the why" of it all?

I think the only thing active and probably will go bad on the PA board are the 2 transistors.? I am sure they can be found, try ebay, and replace them.
I did have the drive transistors located on the main board beside the PA board go bad and did replace them, this was 20 years ago when my first PA board died from storing batteries in the rig for like 6 months.

This is the first I've heard of replacement FT-817 PA boards being unavailable.
Such a rumor, even if not true, runs the very real risk of starting a 'run' on these boards by FT-817/818 owners...
I wonder if it would also be wise for an FT-817/818 owner to secure a replacement display module as well, as long as they are still available?
Please report back your findings Mike,

? Gang,

from what Ive been reading, it doesn't sound good for the home team. I plan on calling yaesu tomorrow afternoon and find out the status of the PA replacement board.
?
So, two questions;
?
Has anyone actually replaced the active MOSFETs on the PA board? I watched Peter from TRX Bench do it, and it look daunting.
?
And two, incase there are no replacement boards from the factory, any one have a spare PA board they are will to sell?

Re: Blown final club? I think I have a membership
I am on my 3rd PA board for my FT817non-ND I bought around 2004.? Both replacements I got from Yaesu, cost about $60 for the PA board assembled and ready to install.? Last one was probably 5 years ago so need to check with Yaesu.
Comes with install instructions, takes a little soldering.? Also look on the FT817 site for installing for one needs to reverse the input and output RF connections.

The critical step ?is the Kaplan tape . Quickchip might make ?removing the heat sink a bit easier.

Re: Blown final club? I think I have a membership
Hi yes I have done it,
It will be a big help to use a hot plate, I used at the time a swan multi cooker and removed the slow cook pot,
So I could put the final unit on to the hot metal pan,
I also have a metcal soldering iron,
Give it a go,
Good luck
