SOURCE: Finals for a Cobra 85 Home Base CB and hom many?

Not familiar with the 35......If it is a ssb radio it will have a pre driver and a pair of finals. they are located on the right side towards the back or along the rear of the chassis to the right. You may have the type of circuit that has a protector diode piggy backed ..they could cause that tyoe of failure also, but in the years I have serviced radios they do not fail too often. I WOULD SUSPECT THE FINALS.

Check bias and check your SWR. Also make sure your coax is not excessively leaky, and also check the loading coil inside the antenna to make sure the coil connections have not become all corroded and that their connections are sound.

first of all are you sure its a bad antenna. I can key the mic with no antenna hooked up and nothing will happen the the finals but you may key it down with a brand new antenna and burn them also.Lokk and see how they are connected in the radio before you take it out and replace it the same way.You may want to replace your driver also.

How do I adust the watts on my cobra 29 ltd CB


Replace the 2314 driver withe a 2SC2166 driver and the final transistor with a 2SC1969 final transistor. Re-tune coils L10,L9,L8 for maximum power. Don't cut d11 like some may say to. It will turn your radio into a crappy sounding radio. Simply adjust VR4. Never cut a limiter. This will get you some solid sounding power.

29 ltd classic wont transmit


Hi,
Great radio when it works.
If you have your settings on CB - not PA - -be sure that your Cobra has that setting selected.
If CB -is selected and still nothing - be sure you have a working mic. These wires are fragile and can break internally. One easy way to check is to borrow a cobra mic or even drop by a CB repair shop and ask them to do a mic check with the mic - it is free.

If you have a bad mic replace it and all should be well.
If your mic is good and it still doesn't transmit you will need to replace the finals in the unit. It is common that these burn out of you got too close to someone with too powerful a radio. The CB shop will need to look at it further and repairs should not be over about 40.00.

Good luck with your Cobra.
