So I have a new couple month old cobra 25 ltd. I blew it up testing amps meaning the radio would pop a fuse everytime the radio was turned on. So I replaced the final, driver and pre driver transitor. The radio now turns on and the tx light changes red when mic is keyed but shows no carrier/modulation and meter does not move on radio. The receiver works and meter moves on receive. The pa works so I believe the audio chip is good. Any suggestions would be greatly appreciated. I replaced a couple 1000 uf caps with no luck. Thanks!
