I am restoring an old ICOM 202 SSB 2 meter portable. I have determined, the final transistor a 2SC-1947 is bad since I have zero output but monitoring the driver signal it is clear and intelligible. I would like to replace it with a transistor with similar ratings but possibly more power output than the 3 watts specified for the ICOM-202. I have repaired these little rigs before, and this "New" one, I would like to try a different transistor than the 2SC-1947 if available. I have already order 2 of the 1947's, but would like to know how to search or compare to a transistor with more power gain but yet operate within the same circuit parameters with minor adjustments.
