Just came across this news release this morning. I have 2 very well known tube amps and built a W6PQL SSPA with a pair of BLF188XR devices after one of the tube amps failed. The home-built solid-stat

As primarily a lurker in the Amps group, and an admitted geek (prior electrical engineer-not that all EE's are geeks) I am aware there are quite few really sharp cookies in amateur radio and those wh
