Hi all.
I'm working on this genny and due to low r.f. output I'm thinking the disc sealed triode may be low, it's a TD03-10. A few more checks to do yet, but anyway I would like to know how to remove it. I'm guessing the black grooved heat sink / shield unscrews, and releases the triode. It looks like someone has allready had pliers on it. Colin
