The only good it would be for is an amp for your QRP rig. You could take the board out and mount it in a larger enclosure so you could also fit a low-pass filter board and bandswitch in with it. It's a broadband amp with those input and output transformers on it so it should operate down into the 160m band (of course, depending on the transformer core mix/material). It may not be worth you time but sometimes it's fun to play around with repurposing stuff like this. Another plus would be taking another dirty amp away from some chicken bander.
