Hi Pat,
Someone posted a in this email showing how the guy from TRX bench replaces the finals. It's not for everyone but he did it with basic tools.
I have attached a picture of the final board (front and rear view). I
have done a lot of radio repairs and soldering in my career and I'm not
sure I would even know where to start to remove the final from this
board. This is a failed final from an early FT-817 (Non ND).

Also if you're sure that it's just a transistors fault the same mitsubishi that came with my 817ND can be bought relatively cheap from major retailers. IIRC it was 7 euros each about a year ago.? Original 817 uses an older model, and a different board which I don't know how easy to find it is.
