Dick, the company I work for repairs a 75 MHz 100 watt FM transmitter that 
uses the SD1460 in the 100 watt final amp.  They have been used for 20+ 
years and are a pretty rugged, cost effective part.  I do not know about 
linear application, these transmitter are class C. I would also be 
interested in any results you may have using them in a linear application.
