Over the past weeks I had KF5FBR’s Yaesu FT101E ad N5WSA’s Icom IC-718 on my bench for various services. The FT-101 needed a general health check and brand new capacitors. No output powers was the problem the IC-718. The latter was caused by burned out final transistors. While working on them, I shot some pictures that I would like to share here.
Let’s start with the Icom IC-718:
Output filter section of the Icom IC-718
One of the two burned out final transistors of the IC-718
Driver section of the IC-718’s final amplifier
And now on to the Yaesu FT-101E:
Plenty of old caps, cobwebs, and dust on this FT-101E module
