    Good morning,no,still need to go over the radio, no transmit or receive, voltages are fluctuating all over. I am thinking either Voltage Regulator or Final. What would be your guess, as this voltage fluctuating is going from 13v to 0v to any volt, all over,but not passed 14v. Going to lift...

I have I think I may have found another issue,take a look at the driver. What do I see, a Crack going down the side. Now will this also play a part in burning up...

    This all happened when replacing L7, but I think L7 was not producing any voltage, just making a noise, traveling to Tr8 this is why I changed the L7,as it did not make a change on my oscilloscope.

    Cobra 29 LTD Cl,assic R58 keeps burning? ( Replaced L7 ) 3 Times

    R58 keeps burning up, after replacing L7,LA111, 3 different LA111. Lifted legs on Driver Final, and Amp, replaced Voltage Regulator, no good. All I did was replace this for a noise, and would not adjust, was over tightened. Any ideas where to start? Thank you, enjoy your day,,,,,
