    Cobra 25 LTD Classic, no voltage change tuning

    Hey Bud, I recapped the 25, I have TX now, it putting out 25 to 30 watts. YES,I had some time, went recapped the whole think, and 2 caps showed up bad on the tester, did not even read them. I believe it was a 33pf 10v that was bad, and a C45 33pf 50v. OK,I have great swing, but I have NO...

    Cobra 25 LTD Classic, no voltage change tuning

    OK,I just notice on my next step is that I am not producing any 16MHz for the second half of my TX. I changed the Can, still nothing, and I do have a TA7310P in case I need one. Off to the races, going to find the missing MHz.

    Cobra 25 LTD Classic, no voltage change tuning

    OK, I will do a little tracing, and see what I come up with. I will go to that section, block the next section off and trace that circuit. Been getting some use out of the Block Connectors Kit, I can block off anything I like, and go to town.

    Cobra 25 LTD Classic, no voltage change tuning

    Hey, thanks, when I put my mind to something, I try my best to get it done. I know this radio is a dime a dozen, but this radio is under my skin, been up till 4 in the morning reading and trying to diagnose, the point I am trying to prove is that a broken radio can be repaired by anyone who puts...

    Cobra 25 LTD Classic, no voltage change tuning

    Andy, about then Voltage,,I went ahead and replaced the D12, D18, D3, D20, D2,which I think it called for a 9.4 Volt, which I put in a IN4740A. On pin 4, all I have is 00.185 Volts.That may be a issue, as it seems a bunch of resistors do not have any voltage at all, 0 volts on both ends of...

    I have a decent amount of knowledge of the basics of a radio workings, I am a bit green on the subject, but I am learning as I go. I am not a dummy, I have the basic repair knowledge of how a CB radio works. I understand that the radio does not have the voltage in all places, but I have aligned...

    Cobra 25 LTD Classic, no voltage change tuning

    Hey Handy Andy, I may have to recheck the Caps, I did replace them all, it is possible that one may have or be shorted out. I cannot set the voltage as there is no voltage upon setting the 3.2 Volts on the first procedure of the alignment according to the Cobra service manual. I shall hopefully...

I am going to peek at the Schematics and see if I can see anything down the line. What I meant on the last post is I did try to align it the...
