Yes, Robb is correct. Those are the companion parts that I am speaking of. They can be bought thru Copper, H&Y, RF Parts and some CB shops.

 

I've been doing MOSFET mods on these boards for a few years now, but I wasn't going to post information about it if I didn't think it wouldn't be reliable, or if the mods caused the radio to perform poorly. Certainly nothing new, but useful if someone wanted to experiment, or wanted to keep costs down when replacing finals.

 

The first D858 Washington I did is still in service today, it's been over 3 years. Still sounds good, still puts out about 25W on SSB.
