Hi all, although not a new subject, now that there are many more users, I'm hoping to get some direction to fix the problem. My friend had his Bitx working but added a speaker and accidently hit the PA/IRF510 tab to the frame of the speaker. He had added a 2 amp fast acting fuse and it blew. 4-5 fuses later, he realized where the short was but the radio still won't transmit. He replaced the PA, still no luck. If you have any experience in this area of the Bitx, what other component(s) might have been affected by this error? He tried to set bias again but gets no bias current reading. Thanks
